Which expression, when simplified, is equal to 7p? a) 9p – 2pq – 7p – 5p + 2pq b) 9p – 2pq – 7p + 5p – 2pq c) 9p + 2pq – 7p + 5p – 2pq d) 9p + 2pq + 7p + 5p – 2pq e) 9p + 2pq – 7p + 5p + 2pq

C

Step-by-step explanation:

2pq - 2pq is zero. B and E have no zero pq coefficient.

p(9-7+5) = 7p

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
