Question

Expand (6y-2y+5y)9 and factor 80-10y. I will give brainliest

Answer 1

Answer:

45y-18y+54y & 10(8-y)

Step-by-step explanation:

For the first problem, you need to distribute the 9 to the 5y, -2y, and the 6y

If you do this and multiply the 9 by each of the terms you get:

45y-18y+54y

Now we can work on the second problem

When factoring, we have to find a common factor.

In this expression, the common factor is 10 because both 80 and 10 are divisible by 10!

So we but the 10 on the outside of the parentheses and divide 80 and 10 by 10 which gets us an answer of:

10(8-y)

If you were to distribute this, you would get 80-10y so we know it is correct

Hope this helps, have a great day, and please award brainliest!

Answer 2

(6y-2y+5y)9

= 54y-18y+45y

80-10y

=10(8-y)
