The cube root of 12 which is c
Answer:

Step-by-step explanation:
We have the different denominators.
The common denominator is 10.

We can subtract these fractions now.

Let x=number 1 let y=number2
there sum is equal to 70
then
number1+number2=70
substituting
x+y=70
y=70-x
let there product will be p
p=xy
substituting
p=x(70-x)
which is choice c
