<h2>Answer: g(f(2)) = 11</h2>

Step-by-step explanation:

g(f(2)) is substituting the value of f(2) for x in g(x). But we must first find f(2).

We know that f (x) = ax² - 12

Since f(3) = 24

⇒ a(3²) - 12 = 24

9 a = 36

a = 4

∴ f(2) = (4)(2²) - 12

= 4

⇒ g(f(2)) = 2(4) + 3

= 11

-- The area of the long skinny piece on top is (6 x 33) = 198

-- The length of the dotted line between the top and bottom pieces is (33-21) = 12

-- The area of the bottom piece is (12 x 15) = 180

-- The area of the whole thing is (198 + 180) = 378

-- The perimeter of the whole thing is (33 + 6 + 21 + 15 + 12 + 15 + 6) = 108

Answer:

g(h(- 8)) = 119

Step-by-step explanation:

Evaluate h(- 8), then substitute the result obtained into g(x), that is

h(- 8) = (- 8)² - 2 = 64 - 2 = 62, then

g(62) = 2(62) - 5 = 124 - 5 = 119
