You know that the sides of a square are increased by 2 inches: the expression should be written as (x+2)
The area is 25 square inches
The area of a square is s×s or s²
so it can be solved as:
(x+2)²=25
x+2=5
x=3
<u>The length of the original side is 3 inches</u>
Hope it helps!

Answer:
B. The two tiles are similar because segment PQ is to segment QR is 1 : 3 and segment JK is to segment KL is also 1 : 3.
Step-by-step explanation:
Just took this test!
When you multiply the first equation by 3, you get:
3 × 3x = 9x
3 × y = 3y (but when added, that part gets eliminated)
3 × 3 = 9
So you end up with
9x + 3y = 9
x - 3y = -2
(add)
10x = 7
So your answer is B. 10x = 7. I hope this helps!
