Help me identify these properties?
1.] (r +s) t = rt +st then rt +st = (r+s) t
2.] (3 x 1/2) 7 = 3 x 1/2) 7

1. commutative property of equality
a = b so b = a
2. If the two sides are expressed EXACTLY the same
it is REFLEXIVE property
a = a (any value equals itself)
(3 x 1/2) 7 = (3 x 1/2) 7
If the parentheses are changed around, but not the
order of the numbers, it could be the
associative property of multiplication
(a * b) * c = a * (b * c)
I cannot tell with some of the parentheses missing.
If it were distributive it would look like
7 * (a + b) = 7*a + 7*b
If you only missed typing the first parenthesis
(and the two sides are the same, with nothing changed)
then it is REFLEXIVE.

a million. upload the 1st 2 numbers on your head (32 + sixteen =40 8) Now, upload your answer (40 8) to eight. (40 8 + 8 = fifty six) fifty six 2. Multiply 5 x 9 (40 5) and then multiply 40 5 x -4 (-a hundred and eighty). -a hundred and eighty 3. Subtract 17 from the two factors of the equation. x = -5 4.it rather is the identity assets. (something plus 0 may be the 1st style.) identity assets 5. it rather is the associative assets. (Numbers in a sum could exact be grouped any way you choose for for and you will whether get a matching answer.) associative assets
