Answer:
A
Step-by-step explanation:
4 needs to be × by x and 3 needs to be +
All 3 sides are equal in an equilateral triangle...
2x - 5 = 3x - 22
-5 + 22 = 3x - 2x
17 = x
2x - 5 = 2(17) - 5 = 34 - 5 = 29
3x - 22 = 3(17) - 22 = 51 - 22 = 29
x + 12 = 17 + 12 = 29
as u can see, all sides measure 29 inches
❤hey mate❤

Answer:
<em>28.26 ft^2, 18.84 ft</em>
Step-by-step explanation:
We are given a circle with a radius of 3 feet;
![Area of Circle = \pi * ( r^2 ) = \pi * ( 3^2 ) = 9\pi \\](https://tex.z-dn.net/?f=Area%20of%20Circle%20%3D%20%5Cpi%20%2A%20%28%20r%5E2%20%29%20%3D%20%5Cpi%20%2A%20%28%203%5E2%20%29%20%3D%209%5Cpi%20%5C%5C)
![Circumference = 2 * \pi * r = 2 * \pi * ( 3 ) = d * \pi, d - diameter,\\Circumference = d * \pi = 6\pi](https://tex.z-dn.net/?f=Circumference%20%3D%202%20%2A%20%5Cpi%20%2A%20r%20%3D%202%20%2A%20%5Cpi%20%2A%20%28%203%20%29%20%3D%20d%20%2A%20%5Cpi%2C%20d%20-%20diameter%2C%5C%5CCircumference%20%3D%20d%20%2A%20%5Cpi%20%3D%206%5Cpi)
