Question

Answer this question please.

Answer 1

Answer:

the area of the square ABCD = 7

on the other hand, the area of the square ABCD = (2+x)² = x² + 4x + 4

then x² + 4x + 4 = 7

then x² + 4x + 4 = 4 + 3

then x² + 4x = 3

Step-by-step explanation:

Answer 2

Answer:

see explanation

Step-by-step explanation:

The side of the square = x + 2, thus area is equal to

(x + 2)² ← expand using FOIL

= x² + 4x + 4

Given area = 7 then

x² + 4x + 4 = 7 ( subtract 4 from both sides )

x² + 4x = 3 ← as required
