Researchers estimate that there are 0.53 penguin
nests per square meter of poop. Each nest represents
at least 2 penguins. What is the combined minimum
penguin population on the islands in the chart?

There would be minimum 1 penguin per square meter.

Step-by-step explanation:

Given,

The estimated number of penguin  nests per square meter of poop = 0.53

Also, the minimum number of penguins in each nests = 2,

Hence,

The minimum  penguin population per square meter of poop = nests per square meter × minimum number of penguins in each nest

= 0.53 × 2

= 1.06

≈ 1

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
