Find two numbers that multiply together to equal c which is 12 which is 3•4
And add two numbers that equal to b which is 7 which is 3+4
= (x+3)(x+4)=0
Set each factor to zero

What is the hypotenuse from
the following Pythagorean
triple?
25 in., 15 in., 20 in.
Answers
Answer:
25 in
Step-by-step explanation:
Hypotenuse is the longest side in the right angle triangle. It is proven by the fact that the square of hypotenus is the sum of the squares of the two other sides.
The hypotenuse of the Pythagorean triple 25 in, 15 in, 20 in is 25 in
The Pythagoras theorem is used to find the sides of a right angle triangle. The formula below is used to find the sides of a right angle triangle(Pythagoras's theorem) is represented below
c² = a² + b²where
c = hypotenuse
a and b are either opposite or adjacent sides
A right angle triangle is a triangle that has one of its angles as 90°.
A right angle triangle has the following sides :
HypotenuseOpposite sideAdjacent sideThe longest side of a right angle triangle is the hypotenuse. Base on the Pythagorean triple, the hypotenuse is 25 inches because its the longest side.

Kyle is making a quilt and he has determined he needs 497 square inches of gray fabric and 746 square inches of yellow. How many square yards of each material will he need? Round your answers up to the nearest quarter yard.
Answers
Answer:
0.38 yard² of gray material0.58 yard² of yellow.Step-by-step explanation:
1 yard is about 36 inches.
A square yard in square inches will therefore be:
= 36 * 36
= 1,296 inch²
He needs 497 square inches of gray fabric. In square yards that will be:
= 497/1,296
= 0.38 yard² of gray material
He needs 746 square inches of yellow:
= 746/1,296
= 0.58 yard² of yellow.

Oxygen has a boiling point of -183 and a melting point of -219 What is the temperature difference of the melting point and the boiling point?
Answers
Answer:
Difference = 36
Step-by-step explanation:
Given that,
The boiling point of Oxygen = -183
The melting point of Oxygen = -219
We need to find the temperature difference of the melting point and the boiling point.
Difference = boiling point - melting point
= -183-(-219)
= -183+219
= 36
Hence, the required temperature difference is 36.

Find the limit, if it exists.
Lim (2x^3+x^2+7)
X->2
Answers
Answer:
27
Step-by-step explanation:
In this case, because we have a polynomial where all x-values exist, we can plug the value (x=2) straight into the function:
[tex]\lim_{x \to \ 2} (2x^3+x^2+7)[/tex]
[tex]= 2(2)^3+(2)^2+7[/tex]
[tex]= 2(8)+4+7[/tex]
[tex]= 27[/tex]
The limit of (2x^3+x^2+7) as x approaches 2 equals 27, which makes sense since the value of (2x^3+x^2+7) at x = 2 is 27.

5(x - 8) + 7 = 2
Step 2: Solve for x
Subtract 7 on both sides: 5(x - 8) = -5Divide 5 on both sides: x - 8 = -1Add 8 on both sides: x = 7Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(7 - 8) + 7 = 2(Parenthesis) Subtract: 5(-1) + 7 = 2Multiply: -5 + 7 = 2Add: 2 = 2Here we see that 2 does indeed equal 2.
∴ x = 7 is the solution to the equation.

Since PR is an angle bisector then it divides the opposite side into segments which are proportional to the other 2 sides, that is
[tex]\frac{PQ}{PS}[/tex] = [tex]\frac{QR}{SR}[/tex] , substitute values
[tex]\frac{x+1}{16}[/tex] = [tex]\frac{x-2}{x+1}[/tex] ( cross- multiply )
(x + 1)(x + 1) = 16(x - 2) ← expand left side using FOIL
x² + 2x + 1 = 16x - 32 ( subtract 16x - 32 from both sides )
x² - 14x + 33 = 0 ← in standard form
(x - 3)(x - 11) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 11 = 0 ⇒ x = 11
