Answer 15

i tried to enter a box looking math symbol but that's what came up in openstudy

Answer 16

well that symbol is telling us what operation to perform

Answer 17

you mean it's an unknown operator, that's all?

Answer 18

Just sub x for a and 3 for b?

Answer 19

the operator lets call it o
a o b= a-b(a-2b)
o is an operation that is being defined in terms of operations that we do know

Answer 20

x o 3 =x-3(x-2(3))

Answer 21

k, clear.

Tks.

Answer 22

x o 3=x-3x+18=-2x+18
3 o x=3-x(3-2x)=3-3x+2x^2
so obviously the operation is not commutative
x o 3 does not equal 3 o x
