Answer:
-24 + 16c
Step-by-step explanation:
There are a couple things we need to know here:
- We need to know how to distribute a negative
- We need to know that we cannot combine 24 and -16c, because we can only combine like terms (we can only combine terms that don't have a c with other terms that don't have a c).
To help distribute a negative, we can first write the problem like this:
-1 * (24 - 16c)
So all we're doing is multiplying -1 by 24 and by -16c, which will get us:
-24 + 16c, which is the answer.
Answer:
4(4x + 5)
Step-by-step explanation:
4 goes into both 16 and 20.
4×4 is 16 and
4×5 is 20.
When factoring you put the nunber you factored out typically, in front. Then the remaining factor goes in a set of parenthesis.
This is like undoing distributive property.
16x + 20
= 4(4x+5)
