8 and 9 pls thx guys

Answers

Number 8
the perimeter of rectangle = the perimeter of hexagon
2l + 2w = the sum of the sides on hexagon

Input what are given from the image
2l + 2w = the sum of the sides on hexagon
2(2x + 5) + 2(x) = 2x - 6 + 0.5x + 1.5x + 3x + 1 + 2.5x + 1.5x

Simplify the left side and the right side
4x + 10 + 2x = 11x - 5
6x + 10 = 11x - 5
This is the equation

Number 9
Solve the equation
6x + 10 = 11x - 5
6x - 11x = -5 - 10
-5x = -15
x = -15/-5
x = 3

The solution is x = 3

A trapezoid has an area of 60 square inches. The height of the trapezoid is 5 inches. What is the length of the longer base if the longer base is three times the length of the shorter base?

Answers

Answer:

Step-by-step explanation:

Remark

Let the shorter base = x

Let the longer base = 3x

h = 5

Area = 60

Formula

Area = (b1 + b2)*h /2

Solution

60 = (x + 3x)*5 / 2                Multiply both sides by 2

2*60 = (x + 3x)*5                  Combine like terms

120 = 4x *5

120 = 20x                             Divide by 20

120/20 = x

x = 6

Therefore the two bases are

x = 6

3x = 18

Answer:

C

Step-by-step explanation:

Given f(x)=18x +8, find x when f(x) =14

Answers

Answer:

x = 1/3

Step-by-step explanation:

14 = 18x + 8

Subtract 8 from both sides.

6 = 18x

Divide both sides by 18.

6/18 = x

Simplify.

1/3 = x

Answer:

x=1/2 or x=0.5

Step-by-step explanation:

14=18x+8 so 18x =6 so x=1/2
