Answer:

Option C,  x ≥ -7

Step-by-step explanation:

The given function is f(x) = \sqrt{7+x}

Then we have to find the domain of the given function

The given function is defined only when ( x+7 ) ≥ 0

or ( x + 7 ) - 7 ≥ 0 - 7

x ≥ ( -7 )

Therefore, domain of the function will be x ≥ -7

Option C is the answer.

swat32

Answer:

length = 36 ft; width = 12 ft

Step-by-step explanation:

Let the width be x.

The length is 3x.

The perimeter is the sum of two lengths and two widths, and it equals 96 ft.

3x + 3x + x + x = 96

8x = 96

x = 12

Width = x = 12 ft

Length = 3x = 3(12 ft) = 36 ft
