Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion
7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)
7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer
Answer:
we need to see the picture or diagram that corresponds to these problems
Step-by-step explanation:
I cant help you unless I see the picture/diagram that corresponds to these problems
Answer:
2z^3 - 5z^2 + 4z - 1
Step-by-step explanation:
(2z - 1)(z^2 – 2z+ 1) =
= 2z^3 - 4z^2 + 2z - z^2 + 2z - 1
= 2z^3 - 5z^2 + 4z - 1
Assuming you didn't forget parentheses, it's C. Hope this helped.
