Answer:
72y2-45
Step-by-step explanation:
9y2 + 9(7y2 - 5)
you multiply the 9 by the stuff in the parentheses
9y2 + 63y2 - 45
72y2-45
You will have to form the equation:
1.01+.09x=9.56 Solve for x. Start buy subtracting 1.01 from both sides.
.09x=8.55 Divide both sides by .09
x=95 The call was 95 additional minutes. So...
25+95=120 120 minutes in total. Check your answer by substituting x...
1.01+.09(95)=9.56
1.01+8.55=9.56
9.56=9.56
I hope this helps!

-9 + (9 + 6) - 42
(-9 + 9) + 6 - 42
0 + 6 - 42
0 + 6 - 16
0 + 6 + (-16)
6 + (-16)
