Answer:
r-7
Step-by-step explanation:
Answer: 74
Step-by-step explanation:
The GCF we factor out is 4a
8ab = 4a*2b
16ac = 4a*4c
12a = 4a*3
Each term has been factored so that 4a is a factor
Using those factorizations, we can use the distributive property in reverse
8ab - 16ac + 12a = 4a*2b - 4a*4c + 4a*3
8ab - 16ac + 12a = 4a*(2b - 4c + 3)
Answer is choice A<span />
Since is addition you do the opposite and subtract 12 from 12 and -5 then 12 cancels out and -5-12=-17
