Find the product of

(a-5) (3a+2)

3a² - 13a - 10

Step-by-step explanation:

(a - 5) (3a +2) = a*3a +2*a -5*3a -5*2 = 3a² + 2a - 15a - 10 = 3a² - 13a - 10

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+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.
