Could anyone help me with this question? Thank you!

C

Step-by-step explanation:

We want to simplify the rational expression:

First, we can factor both the numerator and the denominator. This yields:

Cancel like terms:

However, since we canceled a term from our expression, we must place restrictions in order to stay true to the original expression.

Rational expressions are undefined whenever the denominator equals 0. The denominator is (before canceling):

Solve for n. By the zero product property:

Therefore:

By taking the square root of both sides (since we are taking an even root, it is required to have plus/minus):

Therefore, our fully simplified expression is:

Hence, our answer is C!

c is the correct answer

step-by-step explanation:

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
