Answer:
122 = 2(2w +w)
Step-by-step explanation:
If we let w represent the width of the rectangle, then 2w is the length of it. The perimeter is twice the sum of length and width.
P = 2(L+W)
122 = 2(2w +w) . . . . an equation for the description
Answer:
17/7
Step-by-step explanation:
Cross multiply
10y - 10 = 3y+7
7y - 10 = 7
7y = 17
y = 17/7
(approximately)
using the formula ![x^{a/b}=\sqrt[b]{x^a}](https://tex.z-dn.net/?f=x%5E%7Ba%2Fb%7D%3D%5Csqrt%5Bb%5D%7Bx%5Ea%7D)
we can solve the problem
so we rewrite it as ![\sqrt[3]{5^7}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5%5E7%7D)
and get ~42.75
