Answer 4

No sorry I actually got 500

Answer 5

500??

Answer 6

Yeah because 50 + 10= 60 and 50 * 10= 500

Answer 7

let
P = xy
we need to find maxm of xy
y = 60 - x
P = x(60-x)
now find dP/dx

Answer 8

2x-60?

Answer 9

dP/dx = 60 - 2x = 0
x = 30

Answer 10

Is 30 the answer???

Answer 11

yes

Answer 12

- though the 2 integers are the same

Answer 13

- so it might be argued that the answer is 31 - if one integer is larger than the other

Answer 14

Alright thank you so much! And 30 was the right answer.
