Answer:

B) f(g(x)) = 15x² + 18

Step-by-step explanation:

Plug the entire equation of g(x) in for the x in f(x)

f(g(x)) = 5(3x² + 3) + 3

f(g(x)) = 15x² + 15 + 3

f(g(x)) = 15x² + 18

sveticcg [70]

Answer:

$2\frac{38}{125}\ teaspoons$

Step-by-step explanation:

we know that

There are about 125,000 Brine shrimp in 1 pound

1 pound contains 96 teaspoons

There are about 125,000 Brine shrimp in 96 teaspoons

Using proportion

Find out how many teaspoons of brine shrimp represent 3000 Brine shrimp

Let

x -----> the number of teaspoons

$\frac{96}{125,000}=\frac{x}{3,000}\\\\x=3,000(96)/125,000\\\\x=\frac{288,000}{125,000}\ teaspoons$

Simplify

$\frac{288}{125}\ teaspoons$

Convert to mixed number

$\frac{288}{125}\ teaspoons=\frac{250}{125}+\frac{38}{125}=2\frac{38}{125}\ teaspoons$
