Answer:
D, 6 x 3 x 3
Step-by-step explanation:
One area of a square is 3 x 3 there are 6 squares so we multiply by 6 too.
Start finding the slope of the line

using one of the points find the intercept and the standard form

the equation of the line is
The mean is 26 and the MAD is 3.75
Step-by-step explanation:
We have 8 + 12 + x = 29.
Solving, we get x + 20 = 29, x = 9.
Yes as the even times the occurrence of negative signs makes the answer positive.
