Answer:
A
Step-by-step explanation:
just watch and go with the flow
(2x+y2)5 = 32x5 + 160x4y + 320x3y2 + 320x2y3 + 160xy4 + 32y5
B.225/20 =11.25 prr hour
a.225/20=h
Easy, showing work,
using the method FOIL (First,Outer,Inner, Last)
Take, (x+3)(x+5) and multiply,
First,
x*x=

Outer,
x*5=5x
Inner,
3*x=3x
Last,
3*5=15
Add the terms together,

+8x+15 (

+5x+3x+15)
Thus, your answer.
