Answer:
Step-by-step explanation:
I take it that this is some sort of ratio. Start by solving the brackets on the left.
Brackets: 1/3 - 1/10
Brackets: 10/30 - 3/30
Brackets: 7/30
Brackets^2: 49/900
Brackets^2 - 1/5: 49/900 - 180/900
Brackets^2 - 1/5: -131/900
(2/5)^2 = 4/25
The way this read, it should be

Which when you invert and multiply becomes

which finally becomes

Answer:
A) Associative Property of Addition
Step-by-step explanation:
<u><em>Associative Property of Addition</em></u>
Let A, B and C be any three real numbers
A+(B+C) = (A+B) + C
Given data
(20.4 + 3.75) + 4.25 = 20.4 + (3.75 + 4.25)
= 20.4 + 8.0
= 28.4
