The vol. of a cube of side length s is V=s^3.
So, if the side length is 5a+4b, then the volume of the cube is
V(a, b) = (5a+4b)^3. This could, of course, be expanded, using the binomial theorem, but there's no point in doing so.
X = 42
x/3 - 4 = 10
+ 4 +4
x/3 = 14
•3 •3
x = 42
Find the GCF of 88 and 24 first
88=2*2*2*11
24=2*2*2*3
The GCF for 88 and 24 is 8
The GCF for r^18 and r^13 is r^13 (because they both contain r^13 in them)
=8r^13(11, 3)
Hope I helped :)
Pears 15-30
Bananas 20-40
The answer to the question is
5r= 28
r= 28/5
