Answer:
Step-by-step explanation:
So first rewrite the inside of the parentheses as improper fractions:
÷
Now simplify the inside:
÷ 2
Which is:
Answer: b) (5, -2)
<u>Step-by-step explanation:</u>
From point A to point D we have a y-length of 2 and an x-length 1
From point J to point M we have a y-length of 4 and an x-length of 2
Therefore, ABCD: JKLM is a dilation of 2 ⇒ 1 : 2
DC = 1 so ML = 1(2) = 2
move 2 units from M to locate L.

180-119=61
Answer:
-2 sqrt(15)
Step-by-step explanation:
sqrt(-15) sqrt(-4)
We can use sqrt(ab) = sqrt(a) sqrt(b)
sqrt(-1) sqrt(15) * sqrt(-1) * sqrt(4)
We know the sqrt(-1) = i
i * sqrt(15) * i * 2
2i^2 sqrt(15)
i^2 = -1
-2 sqrt(15)
