Answer:
120 sq. ft.
Step-by-step explanation:
a=lw
a=(12x5)2
a=(60)2
a=120
The least common denominator would be 6.
2*3= 6
3*2= 6

(B) (n + 4)(n +22)
When you expand this equation, we get:
n^2 + 4n + 22n + 88
n^2 + 26n + 88
Answer:
C x=17
Step-by-step explanation:
The top and bottom sides have to be equal for the quadrilateral to be a parallelogram
2x-9 = x+8
Subtract x from each side
2x-9-x = x+8-x
x-9 = 8
Add 9 to each side
x-9+9=8+9
x=17
