A nine can go into a 20 two whole times. After that, there's still
some room left in the 20, but it's only enough room for a 2.
X - y = 7.....x = y + 7
x * y = 60
y(y + 7) = 60
y^2 + 7y = 60
y^2 + 7y - 60 = 0
(y + 12)(y - 5) = 0
y + 12 = 0
y = -12....not this one because it is negative
y - 5 = 0
y = 5 <===
x - y = 7
x - 5 = 7
x = 7 + 5
x = 12 <==
so ur 2 numbers are 12 and 5
Hello!
The formula for the volume of a sphere is 
³.
Let's plug in our radius.
As we are not looking for an exact answer,we can look for an answer in terms of pi. Maybe we could multiply our fraction by 1,000.
Therefore, our answer is D.
I hope this helps!
