Answer:

A

Step-by-step explanation:

Substitute x = f(x) into g(x), that is

g(f(x))

= g(3x² - 2x - 1)

= (3x² - 2x - 1)² = (3x² - 2x - 1)(3x² - 2x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

3x²(3x² - 2x - 1) - 2x(3x² - 2x - 1) - 1(3x² - 2x - 1) ← distribute parenthesis

= 9x^{4} - 6x³ - 3x² - 6x³ + 4x² + 2x - 3x² + 2x + 1 ← collect like terms

= 9x^{4} - 12x³ - 2x² + 4x + 1 → A

soldi70 [24.7K]

Answer: Stacey now bakes 36 cinnamon bagels.

Step-by-step explanation:

Given:  Each morning, Stacey makes 20 cinnamon bagels.

She has increased the number she bakes each morning by 80%.

Number of cinnamon bagels Stacey bake = 20+80% of  20

= 20+ (0.80)x 20           [To remove % , divide number by 100, So 80%=0.08]

= 20+16   [(0.80)x 20=16 ]

= 36

Hence, Stacey now bakes 36 cinnamon bagels.
