Question

Answer any question that you can.

Answer 1

9.) 8 - 1, 2, 4, 8
16 - 1, 2, 4, 8, 16

Both’s GCF is 8.


8a + 16ac = 8(a + 2ac)

10.) a = -5
c = -1

9a + 16c


Substitute.


9(-5) + 16(-1) = -45 + (-16)


Answer: -61

11.) -4b - 8c + 12 - 8b + 2c + 6


Combine like terms.

-4b - 8b = -12b
-8c + 2c = -6c
12 + 6 = 18


New expression: -12b - 6c + 18
