Solve the quadratic equation by compeleting the square. x^2 + 8x = 10
The value of x for the quadratic equation is 1.099 or -9.099 .
What is completing the square?
Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial .
To solve ax²+bx+c=0 by completing the square:
1. Transform the equation so that the constant term, c , is alone on the right side.
2. If a , the leading coefficient (the coefficient of the x² term), is not equal to 1 , divide both sides by a .
3. Add the square of half the coefficient of the x -term, to both sides of the equation.
4. Factor the left side as the square of a binomial.
5. Take the square root of both sides. (Remember: (x+q)²=r is equivalent to x+q= ±√ r.)
6. Solve for x .
According to the question
Quadratic equation by completing the square
x² + 8x = 10
As we will try to make complete square of left side
for that
we have to add to both sides of the equation
As
a = 1
2ab = 8
b = 4
x² + 8x + 4² = 10 + 4²
By using the identity ( )
(x + 4)² = 10 + 16
(x + 4)² = 26
x + 4 = ±
x + 4 = ± 5.099
x = 5.099 - 4
x = 1.099
or
x = -5.099 - 4
x = -9.099
Hence, The value of x for the quadratic equation is 1.099 or -9.099 .

Determine whether each series is arithmetic or geometric. Then evaluate the finite series for the specified term number. 2+6+18+ . . . . . . ; n=6
The given series is a geometric series. The sum of its first 6 terms is 728.
To determine whether the series is an arithmetic or geometric one, we need to check how the consecutive terms relate to each other.
If it is an arithmetic series, then:
a(n) = a(n-1) + d
where d is the common difference.
If it is a geometric series, then:
a(n) = a(n-1) . r
where r is the common ratio.
The given series is:
2+6+18+ . . . .
and the number of terms is 6.
In the given series:
a(1) = 2
a(2) = 6
a(3) = 18
Notice that
a(2)/a(1) = 6/2 = 3
a(3)/a(2) = 18/6 = 3
Since the ratio of consecutive terms are constant, then the given series is a geometric series. Furthermore, its ratio, r = 3
Sum formula for the first n term of a geometric series is:
S(n) = a(1) . (rⁿ -1)/(r -1)
Substitute n = 6, a(1) = 2, and r = 3
S(6) = 2 . (3⁶ - 1)/(3 - 1)
S(6) = 2. 364
= 728
We can also evaluate the sum directly. Write all the terms until n = 6.
a(4) = 18 . 3 = 54
a(5) = 54 . 3 = 162
a(6) = 162 . 3 = 486
Hence, the series is:
2+6+18+54+162+486 = 728

In this problem, you will investigate the relationship between same-side exterior angles.
e. Write a proof of your conjecture.
Eight angles are formed when two parallel lines are intersected by a third line that intersects them at an acute angle, known as a transversal line. These angles interact in a number of ways, one of which is the same-side exterior. Both angles are on the same side of the transversal line, as indicated by the word "same-side," and both are "external," or "outside," of the parallel lines, as represented by the term "outside."
When a transversal crosses two parallel lines, it creates an angle between the lines and outside the lines on the same side. Because the alternate interior and alternate exterior angles are the same, and because linear pairs of angles are supplementary, the identical side angles are also supplementary.

Fred started a new e-Commerce business and borrowed $13,100 for 13 years to get the business up and running. The interest is $3916.90. Find the rate.
Round to two decimal places, if necessary.
Simple Interest
The rate of interest is 0.26%
Given,
The amount borrowed by Fred to start a new e-commerce business = $13100.
Time of investment = 13 years.
Interest for the money = $3916.90
We have to calculate the rate of interest.
For simple interest, equation is:
P = IRT
Where,
P = Principal amount
R = Rate of interest
I = Interest
T = Time period
Here,
P = 13100
I = 3916.90
T = 13
Then,
R = P / IT
R = 13100 / (3916.90 × 13)
R = 13100 / 50919.7
R = 0.26%
Therefore, the rate of interest is 0.26%

Is it possible to find a value of $x$ so that the value of the surface area (in square inches) is equal to the value of the volume (in cubic inches)? a rectangular prism with length labeled 9 inches, width labeled 4 inches, and height labeled x inches.
A rectangular prism can have a surface area equal to its volume given the dimensions are 9 inches long, 4 inches wide and x inches high, where x is equal to 7.2 inches.
A rectangular prism is a three-dimensional figure with 8 vertices, 12 edges, and 6 rectangular faces.
If the dimensions of a rectangular prism is:
L = 9 inches
W = 4 inches
H = x inches
then the value of its surface area is equal to the value of its volume.
SA = V
2(lw + wh + lh) = lwh
Substitute the values and solve for x.
2(lw + wh + lh) = lwh
2[(9)(4) + 4x + 9x] = (9)(4)x

Betsy has a bag with three mint sticks eight jelly treats and nine fruit tart chews if she eats one piece every three minutes what is the probability her first two pieces will be a fruit tart chew and a jelly treat
If Betsy has a bag with three mint sticks, eight jelly treats, and nine fruit tart chews and she eats one piece every three minutes, the probability her first two pieces will be a fruit tart chew and a jelly treat is 18.9%.
The probability of her first two pieces being a fruit tart chew and a jelly treat can be calculated as follows,
First, we divide the expected outcomes by the total possible outcomes.
Total possible outcomes = 3(mint sticks) + 8(jelly treats) + 9(fruit tart chews) = 20
Hence,
Probability for fruit tart chew: 9 ÷ 20
Probability for jelly treat: 8 ÷ 19 (as one possibility is considered to be fruit tart chew)
The probability of her first two pieces to be fruit tart chew and jelly treat can be determined by multiplying the probability for fruit tart chew with the probability for jelly treat,
Probability = (9/20)(8/19)
Probability = 72/380 = 0.189
Converting into percentage,
Probability = 0.189 × 100 = 18.9%
Hence, the probability that her first two pieces will be a fruit tart chew and a jelly treat is equal to 18.9%.

The equation of the line in slope-intercept form is y = (-2)x + (-3) .
The equation of a line in slope-intercept form can be written as follows,
y = mx + c equation 1
m in the above equation represents slope of the line and c represents the intercept.
The given equation is 3y + 9 = -6x .
To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as
3y + 9 = -6x
3y = -6x - 9

The perimeter of a rectangle is 398 meters. The rectangle has a length of (12x-3) meters and a width of (8x+2) meters. What are the dimensions of the rectangle?
The value of perimeter of the rectangle is 398, So the length is 177m and breadth is 82m.
What is perimeter of rectangle?
The complete length of a rectangle's outside edge is known as its perimeter. The formula P=2l+2w, where l is the rectangle's length and w is its width, determines the perimeter P of a rectangle.
Given the perimeter of the rectangle = 398
perimeter of rectangle = 2 × (L + B)
Length of rectangle = (12x-3)
Breadth of rectangle = (8x+2)
⇒ perimeter of rectangle = 2 × (12x-3 + 8x+2)
⇒ 398 = 2 × (20x - 1)
