Answer:
see explanation
Step-by-step explanation:
The area (A) of the square = s² ( s is the measure of the side )
Here s = x + 2 and A = 7 , thus
(x + 2)² = 7 ← expand left side using FOIL
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required

Answer:
Simplified, it would be 2x^2+2xy+3y^2+3x+y+1 so that's your answer.
It's not a rational number because it's a continuous decimal. A rational number has an end.
