Find the approximate side length of a square game board with an area of 173 in.
icang [17]

Answer:

13.15 in

Step-by-step explanation:

We know that to get area for a square is

Side x side = side ^2

(normally we would put an algebra for it, but i just write i like this so that it is easier to understand)

OK therfore I can say

Area = side ^2

173 = side ^2

When u bring a square over, it becomes square root

So...

Square root 173 = side

Side = 13.15in

Solve for x.<br><br> 2/3(x−7)=−2
zaharov [31]
2/3x - 14/3 = -2
3(2/3x - 14/3) = -2(3)
           2x - 14 = -6
                   2x = -6 + 14
                   2x = 8
                     x = 8/2
                     x= 4

hope this helps :)
