Answer:
Stretch out both A and B vertically. Please tell me if this helps!
Step-by-step explanation:
Take one side and invert it
(x + 3)(2x + 5)
Given
2x² + 6x + 5x + 15 ← grouping the terms
= (2x² + 6x) + (5x + 15) ← factor each group
= 2x(x + 3) + 5(x + 3) ← factor out (x + 3) from each term
= (x + 3)(2x + 5) ← in factored form
Perimeter = 4 X Sides
P = 4 S
P = 4 (6 )
P = 24
