The factors of a polynomial x² +6x + 8 ( binomial, power of variable x is 2) are equals to the ( x + 2) ( x + 2).

In Mathematics, Factorisation of an algebraic expression is a process of writing the given expression as a product of its factors. These factors can be any type like numbers, variables, or an algebraic expression. To make the factor of a number means to break it up or decompose into numbers such that the multiplication of these can be get the original number. For example, In case of x² – 9 is (x – 3) (x + 3). In other words

(x- 3) and (x + 3) are the factors of x² – 9. We have, a polynomial say, p(x) = x² +6x + 8 and we have to factorize it. Now, x² +6x + 8 ----(*)

Split the middel term of above expression such that sum/difference of split terms is equal to 6x and multiplication of these give 8x².

=> x² + 4x + 2x + 8

group the pairs, => (x² + 2x ) + (4x + 8)

factor each group of pairs,

=> x( x + 2) + 2( x + 2)

Factor out the common term (x + 2)

=> (x + 2) ( x + 2)

Hence, required factors are ( x + 2) (x + 2).

The original cost of the tablet is $70.89 in the given algebraic equation.

A mathematical claim containing two equated algebraic expressions is known as an algebraic equation. When P and Q are polynomials, an algebraic equation has the general form P = 0 or P = Q. The term "multivariate equation" refers to an algebraic equation that has more than one variable.

Univariate equations are algebraic equations that only have one variable. Equations in algebra are balanced by definition. Due to this, the right and left sides of the equation will be equal.

Let the original cost be  x

then

15/100 = 24.99.x

x =  166.6

237.49 - 166.6

Arctan or tan-1 are used to denote the inverse of Tangent.

The ratio of the perpendicular of the triangle and the base of the triangle with respect to the required angle is know as the tangent of the angle. Specifically, tan = (opposite side) / (adjacent side). The inverse tan formula is thus = tan-1[(opposite side) / (adjacent side)] according to the definition of inverse tan.

The reciprocal of the tangent is the cotangent. It is basically just the reciprocal of the tangent, it means that it can be written as the ratio of the base to the perpendicular.

We showed that EFGH is a square by proving that EFGH is a rhombus and all the angles are right angles. This is one of the classic proofs of the Pythagorean theorem.

(a) First, explain why the EFGH must be a rhombus.

In the figure, square ABCD has points E, F, G, and H on each side, so AE = BF = CG = DH, as shown. This means that all four sides of the rectangle EFGH are the same length. This is because they are all congruent with the side lengths of square ABCD. According to the definition of a rhombus, a rhombus is a quadrilateral with all four sides congruent. All four sides of the quadrilateral EFGH are congruent, so it must be a rhombus.

(b) Explain why all interior angles in EFGH must be right angles?

In square ABCD, by definition, all interior angles are right angles (90 degrees). Since the points E, F, G, and H lie on the sides of the square ABCD, the angles EFG and FGH are congruent to the right angle of the square ABCD. Similarly, the angles FGH and HGE are congruent to the right angle of the square ABCD.

Therefore, all four interior angles of quadrilateral EFGH are congruent with right angles of square ABCD, and all four interior angles of quadrilateral EFGH are right angles.

A square is a quadrilateral with all four sides congruent and all four angles congruent at right angles. And since it has already been proved that the quadrilateral EFGH is a rhombus and all its angles are right angles, we know that the quadrilateral EFGH is a square.

The equation of the line of best fit is: y = -1.15x + 102.8 and Using the equation of the line of best fit, the predicted cost is: $62.55

What is the Equation of a Line of Best Fit?

The equation of a line of best fit is represented by the equation, y = mx + b, where m is the slope and b is the initial value.

1. Using two points, (72, 20) and (20, 80):

Slope (m) = change in y / change in x = (80 - 20)/(20 - 72) = 60/-52

Slope (m) = -1.15.

Substitute m = -3 and (a, b) = (72, 20) into y - b = m(x - a)

y - 20 = -1.15(x - 72)

y - 20 = -1.15x + 82.8

y = -1.15x + 82.8 + 20

y = -1.15x + 102.8

The equation of the best line of fit is y = -1.15x + 102.8.

2. Monthly heating cost, y, for a month with an average temperature of 35°F (x) will be calculated by substituting x = 35 into y = -1.15x + 102.8.

The area of the Temasa's doll house is 31.5 square feet.

What is the scale factor?

The scale factor is a ratio that compares the measurements of an object on a drawing or map to the actual measurements of that same object in real life. It is usually expressed as a ratio in the format 1:n (or 1/n) where n is the scale factor.

We can start by using the scale factor of 1:10 to find the actual dimensions of the doll house.

Since the scale factor is 1:10, this means that for every 1 inch on the drawing, the actual measurement is 10 inches. So, to find the actual length and width of the doll house, we can multiply the measurements on the drawing by 10.

7 1/5 inches * 10 = 71 inches + 2 inches

4 4/5 inches * 10 = 44 inches + 8 inches

So, the actual length of the doll house is 71 inches + 2 inches = 73 inches, and the actual width is 44 inches + 8 inches = 52 inches.

To find the area of the doll house, we can multiply the length and width:

73 inches * 52 inches = 3788 square inches

To convert this to square feet, we can divide by 12^2, since 1 foot = 12 inches:

3788 square inches / (12 inches)^2 = 31.5 square feet (rounded to the nearest square foot)

Hence, the area of the Temasa's doll house is 31.5 square feet.

The perimeter of the triangle is given by the equation P = 4√3 feet

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the perimeter of the triangle be P

Let the triangle be represented as LMX

Now , An equilateral triangle is a triangle in which all three sides have the same length.

∠L = ∠M = ∠X = 60° and LM = MX = LX

The height of the triangle is LW = 2 feet

Now , from the trigonometric relations ,

sin 60° = opposite side / hypotenuse

Substituting the values in the equation , we get

√3 / 2 = 2 / LX

Multiply by LX on both sides of the equation , we get

LX ( √3/2 ) = 2

Multiply by ( 2/√3 )on both sides of the equation , we get

LX = 4/√3

Now , the perimeter of the triangle = LX + LM + MX

There are three angles in a triangle ABC. A triangle is a three-sided polygon and it has three angles. Each angle is formed by the intersection of two sides of the triangle.

In a triangle, the angle between two sides is measured in degrees and these angles are formed by the intersection of the two lines that represent the sides of the triangle. The three angles in a triangle are labeled with the corresponding vertex, for example, angle A, angle B, and angle C.

In a triangle, the sum of the three angles is always 180 degrees. This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.

Using Composition of functions, the value of g(h(24)) = 1158.

A function is composed in mathematics when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.

The new function h is created by combining the two functions f and g, where h(x) = f(g(x)) for all x in g's domain where g(x) is in f's domain. Function composition is denoted by the notation h = f • g, also written as h(x) = (f • g)(x), which can be interpreted as "f of g of x."

Given,
