Answer:
B) -9(2 + 3)
Step-by-step explanation:
As the answer choices are showing the backward process of distribution process, just divide common factors and bring them outside.
In this case, the factors of the following numbers are:
18: 1 , 2 , 3 , 6 , 9 , 18
27: 1 , 3 , 9 , 27
The largest common factor is 9. Divide -9 from both sides (since both of them share a negative sign, also factor out the negative sign):
(-18 - 27)/-9 = 2 + 3
B) -9(2 + 3) is your answer.

Answer:
a) The blue whale has about 200 times more mass
Step-by-step explanation:
(blue whale mass)/(cow mass) = (1.8×10^5 kg)/(9×10^2 kg)
... = (1.8/9)×10^(5-2)
... = 0.2×10^3
... = 200
The blue whale has about 200 times as much mass as a cow.
