Ada writes 10+8=18 on the board. maria wants to use to commutative property of addition to rewrite ada's addiction sentence. what number sentence should maria write?

"commutative property" in addition and multiplication means that you can exchange the places of integers in addition and multiplication and still get the same answer.

For this question:

10 +  8 = 18 can be rewritten using commutative property as: 8 + 10 = 18

What Ada should write in order to do the Commutative property of addition is 8+10=18.

10 * 563.67 = 5636.7

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
