Answer:
y = 5, -4
Step-by-step explanation:
To solve proportions you cross-multiply.

Now that we have 8 = y^2 - y - 12, we must make the entire trinomial equal to 0 by subtracting 8 from both sides.
y^2 - y - 20 = 0
Factor the trinomial.
(y - 5)(y + 4) = 0
Make both factors equal to 0 to solve for both values of y.
- y - 5 = 0 --> y = 5
- y + 4 = 0 --> y = -4
y = 5, -4

Answer: 2c^2
Step by step explanation:
Answer:
3(n + 2) > 0
Step-by-step explanation:
Work on a piece at a time.
"sum of a number and two": n + 2
"three times the sum of a number and two": 3(n + 2)
"three times the sum of a number and two is greater than zero": 3(n + 2) > 0
Answer: 3(n + 2) > 0
