Is X^2+16x +8 a perfect square?

No

Step-by-step explanation:

This polynomial is not a perfect square because once put into x method, it does not factor. If you stitch the 16x and 8 so the equation is x^2 +8x + 16 it would be a perfect square of (x+4)^2. Stay Safe!

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
