Subtract the difference from the total, then divide by 2, that would be the age of the youngest, then add the difference to that for the age of the oldest.
37 - 5 = 32
32 / 2 = 16
The youngest is 16.
16 + 5 = 21
The oldest is 21.
The ages are 16 and 21.
It's simple you multiply it out and get 8,370
First of all, this isn't an equation. There's no equal sign, so it's just an expression.
9x^2-27xy
9x(x-3y)
This is now factored. I pulled out the greatest common factor:)
The second one the one that is purple
