By the commutative property of addition, the answer you got
c = -b+5a
is identical to selection ...
D. c=5a-b
The commutative property tells you the order of addition doesn't matter, so
(-b)+(5a) = (5a)+(-b) = 5a-b
(This is one of the reasons we study these properties.)
Step-by-step explanation:
2 x y + x + 2 y is equal to 3 x y + 2 y final answer is 5xy
F(5)=x*10=50
um..
5x+5x+(2x+4)+(2x+4)=50
