What was the amount of the cost of goods sold

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

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.
