He ran m miles last week. his goal this week was to run one mile more than twice the miles he ran last week. if he tripled his goal, write an expression in simplest form to show how many more miles he ran this week compared to last.

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: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

not sure but it may be b, as i said i'm not sure.
