.75x-14=-8
Use inverse operations to find x
Add 14 on both sides
.75x=6
divide by .75 on both sides
x=8
The gcf of 12 and 18 is 6
so
6(2x + 3)
Answer:
Surface area = 505cm²
Step-by-step explanation:
Surface area of the triangular prism. = 2B + ph
B is the base area
p is the perimeter of the triangle
h is the height of the triangle
Base area = 1/2 * base * height
Base area = 1/2 * 18 * 40
Base area = 9 * 40
Base area = 360cm²
Perimeter of the triangle = 41 + 41 + 18
Perimeter of the triangle = 100cm
height of the prism = 45cm
Surface area = 360 + 100 + 45
Surface area = 505cm²

Hello!</h2>
The answer is: The length of the ratio is 18 feet.
<h2>
Why?</h2>
There are two ways to calculate the circumference of a circle:
![C=\pi d\\C=2\pi r](https://tex.z-dn.net/?f=C%3D%5Cpi%20d%5C%5CC%3D2%5Cpi%20r)
Since we are looking for the length of the radius, let's work with the second formula.
From the statement we know that the circumference of the cirble is 36π, so we need to isolate the ratio:
![C=2\pi r\\\\36\pi feet=2\pi r\\\\r=\frac{36\pi feet}{2\pi }=18feet](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r%5C%5C%5C%5C36%5Cpi%20feet%3D2%5Cpi%20r%5C%5C%5C%5Cr%3D%5Cfrac%7B36%5Cpi%20feet%7D%7B2%5Cpi%20%7D%3D18feet)
So, the length of the ratio is 18 feet.
Have a nice day!
