Solve the Problem $\mathrm { P } ( \mathrm { s } ( \mathrm { a } ) ) = 4 \mathrm { a } ^ { 2 } + 20 \mathrm { a } + 27$

Multiple Choice

Solve the problem.
-The population P of a predator mammal depends upon the number x of a smaller animal that is its primary food source. The population s of the smaller animal depends upon the amount a of a certain plant that is its
Primary food source. If P(x) = 3x2 + 2 and s(a) = 2a + 5, what is the relationship between the predator mammal
And the plant food source?

A) $\mathrm { P } ( \mathrm { s } ( \mathrm { a } ) ) = 4 \mathrm { a } ^ { 2 } + 20 \mathrm { a } + 27$
B) $\mathrm { P } ( \mathrm { s } ( \mathrm { a } ) ) = 6 \mathrm { a } + 7$
C) $P ( s ( a ) ) = 12 a ^ { 2 } + 30 a + 77$
D) $P ( s ( a ) ) = 12 a ^ { 2 } + 60 a + 77$
