Answer:
x=16
Step-by-step explanation:
We are given that

we have to solve this equation for x
in order to do that we need to isolate x first
hence
subtracting 11 from both sides we get


Now we square on both sides we get



hence x =16
Answer:
add 18 to both sides, giving you 3x = 96
Answer:
32
Step-by-step explanation:
The formula needed to solve this question by hand is:
![x^{\frac{m}{n}} =\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D)
256^(5/8) = 8th root of 256^5
256^(5/8) = 8th root of 1280
<u>256^(5/8) = 32</u>
The perimeter is 62 inches. My work is shown in the picture.
