Answer:
D
Step-by-step explanation:
This is factor by grouping. In factor by grouping, write a quadratic trinomil as 4 terms and group by parenthesis. Then factor by GCF in each pair. If the two parenthesis match, the factoring has worked and the factors will be the GCFs as one and the parenthesis as one other.
The factors here are the GCFs 
and -3 as 
and the parenthesis (x-5).
Answer:
sine 52 degrees = height / 78
height = 78 * sine 52
height = 78 * 0.78801

Answer:
20 ft
Step-by-step explanation:
We know that
Perimeter of rectangle = 2(l + w)
Let the width be w
=> 104 = 2(32 + w)
=> 104/2 = 32 + w
=> 52 = 32 + w
=> 52 - 32 = w
=> 20 = w
Hence z
