Answer:
2
Step-by-step explanation:
(X-10)(X-10)
You need to first multiply out the brackets. So, first times X by X, which makes x^2 . Then do -10 x -10 which makes 100. You then need to multiply the X within the first bracket with the minus 10 in the second bracket which makes -10x. Do the same but with the -10 from the first bracket and the X from the second which again makes -10x. So altogether you have x^2-10x-10x+100. This can be simplified down to x^2-20x+100. You then do the same thing for the second question :)
Answer:
-2
Step-by-step explanation:
Commutative Property of basic numbers is a property in which you can move around or move the order of the numbers yet still get the same sum or product. This property only applies to the addition and multiplication operations. In which why you might want to consider the commutative property? Well, first thing is that you get the idea that for example, 1 + 2 + 3 = 6 that if you change the order or move around the numbers like 3 + 2 + 1 = 6, you still got the sum. And next is because if will be help for more complex equations like combined operations in a single equation. 1 + 3 – 4 x 6 / 2 = 8 ; 3 + 1 – 6 x 4 / 2 = 8
