Find x and the measures of the indicated parts.

a. x=3/2, ab =3

b. x=3/2, ab=6

c. x=14/3, ab=28/3

d. x=14/3, ab=28

  A. X=3/2, AB =3

Step-by-step explanation:

∆ADC ~ ∆AEB so we have AB/AC = AE/AD:

  2x/(2x+4) = (14-8)/14

  14(2x) = 6(2x+4) . . . . . . . cross multiply

  28x = 12x +24 . . . . . . . . eliminate parentheses

  16x = 24 . . . . . . . . . . . . . .subtract 12x

  x = 24/16 = 3/2 . . . . . . . divide by the coefficient of x; reduce the fraction

Then the length of AB is ...

  AB = 2x = 2(3/2) = 3

The solution is x = 3/2, AB = 3.

x + 4/7

step-by-step explanation:

use cymath

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.
