Last of my points help me in this thanks and God bless you Chanelle deposits $7500 into the bank. She does not withdraw or deposit money for 6 years. She
earns 6% interest during that time.
a) How much interest will she have earned at the end of 6 years?
b) What will the balance be when she is finally able to withdraw the money?

A-450

B-7950

Step-by-step explanation:

7500*0.06=450

7500+450=7950

based on context clues you gave i'm assuming the answer would be c.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
