Solve for x please and explain!

9514 1404 393

  x = 6

Step-by-step explanation:

The parallel lines divide the side lengths proportionally.

  21/14 = (x+3)/x

  1.5 = 1 +3/x . . . . perform the division

  0.5 = 3/x . . . . . .subtract 1

  x = 6 . . . . . . . . . multiply by 2x

answer: about 22.67

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
