Answer:  2

<u>Step-by-step explanation:</u>

f(x) = 2x + 3        g(x) = x² - 1

f(g(x)) = f(x² - 1)

         = 2(x² - 1) + 3

         = 2x² - 2  + 3

         = 2x² + 1

The largest exponent is 2 so the degree is 2.

A forest covers 37 comma 000 acres. A survey finds that 0.2​% of the forest is​ old-growth trees. How many acres of​ old-growth
miss Akunina [59]

74 acres of old-growth are there in the forest

Step-by-step explanation:

To answer the question, we need to calculate the 0.2% of 37,000.We can calculate this stating that exists a linear relationship between the percentage and the number of acres. We also need to state that 37,000 acres are the 100% of the acres.

=\frac{0.2}{100} \times 37000\\ =0.002 \times 37000\\=74

We find that if 37,000 acres are the 100% of the acres ⇒ The 0.2% of the acres are 74 acres (in which there are old-growth trees).
