Answer: See below
Explanation:
(2x + 2y)(x - y) + (2x - 2y)(x+y)
= 2(x+y)(x-y) + 2(x-y)(x+y)
= 2(x^2 - y^2) + 2(x^2 - y^2)
= (2 + 2)(x^2 - y^2) (combine like terms)
= 4(x^2 - y^2)
It is 9078 because compounded annually
Elise’s number is 24
-56 divided by -7 is 8
8 + 16 is 24
basically you just do everything in reverse
here is the picture for this question
ALSO MY GUESS WOULD BE A 2 COULUM
I think -3; If the final par was -8, you would subtract (-4 + 2), you would get -6. Then you just divide it in half because it said he scored the same in rounds 3 and 4, leaving you with -3.
