Whoever can answer this is awesome and is a genius plz urgent

the side length is 30 feet

Step-by-step explanation:

we are given cost equation as

where

C is the cost in dollars

n is a side length in feet

we are given

cost is $355

so, C=355

we can set C=355

and then we can solve for n

we can subtract both sides by 175

Multiply both sides by 5

now, we can take sqrt both sides

So,

the side length is 30 feet

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
