7m^2 - 11m - 2
<h2><u>
Step-by-step explanation:</u></h2>
Distribute the negative.
4m^2 - m + 2 + 3m^2 - 10m - 4 = ?
Now, add the like terms.
4m^2 + 3m^2 = 7m^2
-m + (-10m) = -11m
2 + (-4) = -2
7m^2 - 11m - 2

The variance is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 21
The sum of squares is 
Generally the variance is mathematically represented as
substituting values
Answer:
A = 8x^2
B = 6x^3
C = -23x
Step-by-step explanation:
A: -4 * -2x^2
A: 8x^2
B: -3x * -2x^2
B: 6x^3
C: -8x -15x
C: -23x
