Answer:
O equivalent by the associative property of addition
Step-by-step explanation:
Associative Property = a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result
Which means that you can change the expression 25x - (6x+12) without changing the answer. So, the changed result would be (25x-6x) + 12.
Answer:
132
Step-by-step explanation:
What you have to find is what numbers add to -6 and multiply to 9. these numbers would be -3 and -3 (-3+-3=-6, -3*-3=9). substitute these in for -6x as x^2-3x-3x+9=0. then factor out c and three to get x(x-3)-3(x-3)=0. x-3=0 in both cases, so x is three.
Answer:
yes it is a rational number
