You will need to use FOIL for this, or distribute.
So you will multiply -7y and 5y, then -7y and 3
Multiply 2 and 5y, then 2 and 3
You will get: -35y²-21+10y+6
Combine like terms:
-35y²+10y-15
There you go!

Answer:
answer is 2
Step-by-step explanation:
Answer:
m + n = 26 and n = 2m + 5
m = 7, n = 19
Step-by-step explanation:
Because we know that the sum of m and n is 26, we get the first equation. For the second equation, we are told that n is five more than twice m. So we multiple m by 2 and then add 5 to that to get what n is. This is our second equation.
We plug the second equation in for n in the first equation to get
m + (2m + 5) = 26
3m + 5 = 26
3m = 21
m = 7
And then for n, we solve the first equation to get
7 + n = 26
n = 19
