Answer:
um... you are wrong
Step-by-step explanation:
its the the last one
you can't add when its division
you can change exponents from 1/x^-2
to x^2

45% right if .5 x 90 = 45 and as a percentage it would be 45%
30.66pi ft³
First, we need to find the volume of the cylinder using the following equation
![V = r^2h\pi \\V = (2^2)5\pi \\V = (4)5\pi \\V = 20\pi](https://tex.z-dn.net/?f=V%20%3D%20r%5E2h%5Cpi%20%5C%5CV%20%3D%20%282%5E2%295%5Cpi%20%5C%5CV%20%3D%20%284%295%5Cpi%20%5C%5CV%20%3D%2020%5Cpi)
The volume of the cylinder is 20pi
Next, we need to find the volume of a sphere. Since the cylinder is divided in half by the cylinder, we can use the following equation as if it were whole
![V = \frac{4}{3} r^3\pi \\V = \frac{4}{3} 2^3\pi \\V = \frac{4}{3} 8\pi \\V = 10\frac{2}{3} \pi](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20r%5E3%5Cpi%20%5C%5CV%20%3D%20%5Cfrac%7B4%7D%7B3%7D%202%5E3%5Cpi%20%5C%5CV%20%3D%20%5Cfrac%7B4%7D%7B3%7D%208%5Cpi%20%5C%5CV%20%3D%2010%5Cfrac%7B2%7D%7B3%7D%20%5Cpi)
The volume of both half spheres is 10.66pi
Now we can add both together to get 30.66pi ft³

Answer:
<h2><em><u>28</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>12x</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
Sides of a square is = 7 + 3x
<em><u>Therefore</u></em><em><u>, </u></em>
Perimeter of a square = 4 × side
= 4 × (7 + 3x )
= <em><u>28 + 12x (Ans)</u></em>
