Answer:
(x + 7)(x + 8)
Step-by-step explanation:
![{x}^{2} + 15x + 56 \\ = {x}^{2} + 8x + 7x + 56 \\ = {x}(x + 8) + 7(x + 8) \\ = \huge \red{ \boxed{ (x + 8)(x + 7)}}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%2B%2015x%20%2B%2056%20%5C%5C%20%3D%20%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%208x%20%2B%207x%20%2B%2056%20%5C%5C%20%20%3D%20%20%7Bx%7D%28x%20%2B%208%29%20%2B%207%28x%20%2B%208%29%20%5C%5C%20%20%3D%20%5Chuge%20%5Cred%7B%20%5Cboxed%7B%20%28x%20%2B%208%29%28x%20%2B%207%29%7D%7D)
Answer:
22
Step-by-step explanation:
The line where it says 2cm, extend that line to the top. You know have 2 triangles, call the one on the left A and the one on the right B
area of recntangle = bh
Rect A:
b = 5
h = 4 - 2
h = 2
bh = 5 x 2
bh = 10
Rect B:
b = 3
h = 4
bh = 4 X 3
bh = 12
Total = 10 + 12
Total = 22
I believe the answer is A because the formula for area is length times width.
