Give the numerical coeffiecent of
6m exponet 2

If you are talking 6 m^2, the coefficient is 6.

Simplify the expression and combine like terms
3t+4(13t)
how do i do this? 
3 t + 4  12 t
4  9 t 
How did you get the number 9?

3 t and 12 t
are like terms. 3 of them  12 of them is 9 of them
If t were dollars, we would have 3 dollars 12 dollars, which means we owe 9 dollars
