Find x if AC = -7+2x, BC =9, and AB = -27 + 3x

x = -4

Step-by-step explanation:

AB + BC = AC

-27 + 3 + 9 = -7 + 2x

-27 + 3 + 9 + 7 = 2x

-8 = 2x

x = -8/2

x = -4

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

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
