Answer: -1
Step-by-step explanation: A typical quadratic equation is 
and the maximum value formula is -b/2a, so let plug it in -4/2(-4) which equals 1/2. Then let plug 1/2 into the equation,
-4(1/2)^2+4(1/2)-2=
-1+2-2=
-1
15. 5 times 3 is 15.
If you check, 15 divided by 3 is 5(red cars).
This is the associative property, since any numbers can <em>associate </em>with each other, via the parentheses.
Easy just divide by 2 :)))
