Answer:
A. StartRoot 3 EndRoot.
Step-by-step explanation:
We have to simplify the following expression
Now, we know that 27 = 3 × 3 × 3, hence .
And 12 = 2 × 2 × 3, hence
So, the given expression becomes
= 2 × 3√3 + 2√3 - 3√3 - 2 × 2√3
= 6√3 + 2√3 - 3√3 - 4√3
= √3
Therefore, the solution is A. StartRoot 3 EndRoot. (Answer)
Answer:
84
an 84 on the last exam would give the student an 80 for the marking period
So here, I would first multiply 0.17777.... (Assume that that's x) by 10, then you get
10x = 1.777777...
And then subtract x from 10x and then you get 1.6.
So that means that
10x - x = 9x
and 1.7777... - 0.17777... = 1.6
So now to solve for x, divide both sides by 9
To get 1.6/9 = x
Or 16/90 = x
Or 8/45 = x
(That explanation made no sense)
