How do I simplify this ? -5xy(6xy3-4xy+7y2)

this is it simplified ((−5x)(y))(6xy3−4xy+7y2)

Step-by-step explanation:

and step by step

=((−5x)(y))(6xy3+−4xy+7y2)

=((−5x)(y))(6xy3)+((−5x)(y))(−4xy)+((−5x)(y))(7y2)

=−30x2y4+20x2y2−35xy3

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
