What do you need help with?
The GCF of the three terms (9a, -18b and 21c) is 3
Rewrite each of the terms so 3 is a factor
9a = 3*3a
-18b = -3*6b
21c = 3*7c
So we can say...
9a - 18b + 21c = 3*3a - 3*6b + 3*7c
9a - 18b + 21c = 3(3a - 6b + 7c)
Answer: 3(3a - 6b + 7c)
If you distribute outer 3 to each of the inner terms and multiply, you'll get the original expression again.
Answer:
D
Step-by-step explanation:
Answer:
the fourth one is the answer
15x^5 + 12x^4
you multiply the coefficients and add the exponents
A = P(1+r/n)^<span>(nt)
A = 32,000(1+0.03/4)^28
A = 39,446.78 ...........this is your answer</span>
