Factor the following using GCF and show work. 4x^5-28x

d. is the correct answer

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

tip $2.90

total $17.40

the answer to this is a. a^2 + b^2 = c^2
