Answer:
28.8 and 180
Step-by-step explanation:
you just times B by 2/5 to get C and divide it by 2/5 to get A
C = (72)(2/5) = 28.8 km³
A = (72)/(2/5) = 180 km³
We know the answers make sense because A shrinks to get B and B shrinks to get C, and our answers match that.

Answer:
y=2x^2+1
Step-by-step explanation:
I checked on photo maths
First multiply 3 and the 1
Then simplify b^2-4b+3=0
Then divide both numbers by 3 (b-3/3)(b-1/3)=0
If it doesn’t go in even like the second term then bring it before the B
Then equal both terms to 0 and solve
