Answer:

a \: \:  x =  \frac{ -1 ±  i\sqrt{139}}{14}

Explanation:

Since this is unfactorable, use the Quadratic Formula:

x =  -b ± \frac{ \sqrt{ {b}^{2} - 4ac}}{2a}

Now, take the information and input it:

-1 ± \frac{ \sqrt{1 - 4(7)(5)}}{2(7)} \\  \\ -1 ± \frac{ \sqrt{ -139}}{ 14} = \frac{-1 ±  i\sqrt{139}}{14}

I am joyous to assist you anytime.

Let s be the side of square cardboard

We know that perimeter of square =f(s=)4\times side

Then, perimeter of  cardboard=4s

4s\geq 92

Dividing by 4 on both sides

s\geq 23

Hence, the domain of function[23,\infty)

Therefore, option d is true.
