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:
29.92 m² (nearest hundredth)
Step-by-step explanation:

Area of rectangle = width × length
⇒ area = 4 × 5.5 = 22 m²
Total area = area of sector + area of rectangle
⇒ total area =
= 29.91943148... = 29.92 m² (nearest hundredth)
