Answer:
P(x,y) = -x²+62x
Step-by-step explanation:
if x and y are the numbers, then x+y = 62. We put y in function of x; y = 62-x. The product of x and y can, therefore, be represented as a function over the variable x only
P(x,y) = x*y = x*(62-x) = -x²+62x
This function represents the result of the product of x with y.
I hope that works for you!
