Answer:

x is 7

EF is 10

FG is 12

Step-by-step 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

The right question is that the lowest altitute is 3^8 feet

You are told that the highest altitude is 3 times the lowest altitude =>

highest altitude = 3 * lowest altitude = 3 * 3^8 feet.

Now you use the ruel of mutiplication of powers with the same base: copy the base and sum the exponents => 3 * 3^8 = 3 ^(1+8) = 3^9.

Note: remember that 3 = 3^1.

Answer: 3^9 feet
