Answer:
n+18
Step-by-step explanation:
A number n just means a variable n, and since we are increasing it (or adding to it), by 18, it is n+18
Answer:
There is no solution for this set of equations.
The sum of two numbers can not have two different solutions.
I think it might be false, I could be wrong though.
Hopefully that helped! :)
Answer:
adjacent, x=15
Step-by-step explanation:
the angels are connected so they are adjacent, the red box shows that it is a 90 degree angle so adding both angels together means 90=6x so x=15
3M^2 + 11MN + 6N^2 = 3M^2 + 2MN + 9MN + 6N^2
= M(3M + 2N) + 3N(3M + 2N) = (3M + 2N)(M + 3N)
Answer: 3M^2 + 11MN + 6N^2 = (3M + 2N)(M + 3N)
