X/24 = 25/100
100x = 600
100x/100 = 600/100
x = 6

A whole pizza has 8 slices. 1/4=25%. 25% of 8 is 2.
The answer is (x-y)^2
hope it helps!!!!!!
the formula is
(a-b)^2
and when you expand it, it becomes
a^2-2ab+b^2
It doubles every 4 hours, so after 24 hours there will be 6 doublings.
2^6 = 64
So, the population will be (3,000,000 * 64) or 192,000,000 in 24 hours.
The answer is B.
