Answer: -6x² + 15x + 5
Step-by-step explanation:
To solve this problem, you only need to substitute g(x)'s equation as the value of the x in f(x), then simplify.
Step 1: f(x) = -3(2x² - 5x - 1) + 2
Step 2: Apply the distributive property
-3(2x²) + -3(-5x) + -3(-1)
-6x² + 15x + 3
Step 3: Simplify
f(x) = -6x² + 15x + 3 + 2
f(x) = -6x² + 15x + 5

Answer:
3 1/3 cups
Step-by-step explanation:
one and one half dozen = 1.5 * 12 = 18 cookies
18 cookies 90 cookies
---------------- = -------------
2/3 cup x cups
using cross products
18 * x = 2/3 * 90
18 x = 60
divide each side by 18
x = 60/18
divide top and bottom by 6
x = 10/3
change the improper fraction to a mixed number
3 goes into 10 3 times with 1 left over
x = 3 1/3 cups
