Answer:
M=p-5n
Step-by-step explanation:
Here we are given that M+5n=p
We are asked to solve this equation for M. In order to do that we will follow these steps.
Subtracting 5n from both sides we get
M+5n-5n=p-5n
M=p-5n
Hence , now we have our M as dependent variable, whose value depends on the values of p and n. One or both of them can be independent variable/.
Answer:
x=45
Step-by-step explanation:
this should be right
If (x+2) is a factor of 3x^2+14x+k, the equation must equal zero when x=-2 so:
3(-2)^2+14(-2)+k=0
12-28+k=0
-16+k=0
k=16
