Answer 1

x is 7

EF is 10

FG is 12

Explanation:

`EF + FG = EG \\ (4x - 18) + (3x - 9) = 22 \\ 7x - 27 = 22 \\ 7x = 49 \\ x = 7`

then substitute:

`EF = 4x - 18 \\ EF = 4(7) - 18 \\EF = 28 - 18 \\ EF = 10`

`FG = 3x - 9 \\ FG = 3(7) - 9 \\FG = 21 - 9 \\ FG = 12`

First question:

BC + BA = CA

BC = CA - BA

BC = 36 - 9

BC = 27
