Multiply the polynomials. (x2−4)(x2+3x−5)

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.

139 divided by a number

step-by-step explanation:

35/2 is it i think maybe

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
