Answer:
Step-by-step explanation:
The number of miles that he ran last week is m.
His goal this week was to run one mile more than twice the miles he ran last week. This means that his goal this week is
m + 2m = 3m
If he tripled his goal, it means that the number of miles that he ran this week would be
3 × 3m = 9m
An expression in simplest form to show how many more miles he ran this week compared to last week would be
9m - m = 8m

Answer:
B and D
Step-by-step explanation:
This is because for B you do 8x9x1 which is basically 8x9 which is 72. Then, for D you do 12x3x2. Do 3x2 first and you get 6. Then, do 6x12 which is also 72. So the correct answers that will give you the volume of 72 units cube is B and D. Hope this helps!
Step-by-step explanation:
3(x - 4y) - 2(y + 7x)
= 3x - 12y - 2y - 14x
= 3x -14x -12y -2y
= -11x -14y
