Question

if the side of the square is 4x+5 and the area is 625 find x

Answer 1

area of the square=side^2

so 625=(4x+5)^2

square rooting both sides

25=4x+5

25-5=4x

20=4x

x=20/4=5

Answer 2

$side = 4x + 5 \\ area = 625 \\ {side}^{2} = 625 \\ (4x + 5) {}^{2} = 625 \\ 4x + 5 = \sqrt{625} \\ 4x + 5 = 25 \\ 4x = 25 - 5 \\ 4x = 20 \\ x = \frac{20}{4} \\ x = 5$
