Which statements include two quantities in the real world that are additive inverses?
select  each  correct answer.

a rock climber ascends 14 feet and then descends 14 feet.

a child skips 12 feet to the right and then skips 9 feet to the left.

a person removes 8 books from a bookshelf and puts 8 books back on the bookshelf.

a person deposits $200 in to a bank account and then withdraws $80 from the account.

A. A rock climber ascends 14 feet and then descends 14 feet.

Step-by-step explanation:

An additive inverse is an equation that always ends in zero.

14 - 14 = 0

y = x + 95

y = 42 + 95

y=137 mm hg

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
