Afootball field is 100 yards and also includes two endzones that are 10 yards long each. how many feet long is a football field including the endzones?

360 feet long.

Step-by-step explanation:

We have been given that a  football field is 100 yards and also includes two end zones that are 10 yards long each.

Let us find the length of both end zones by multiplying 10 by 2 as field includes to end zones.

To find the total length of football field we will add the length of both end zones to the length of football field.

Let us convert 120 yards to feet by multiplying 120 by 3 as 1 yard equals to 3 feet.

Therefore, the football field is 360 feet long including the end-zones.

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
