To simplify use the distributive property first. Multiply 6 by each value inside the parentheses:
6(x-4) + 9
6x -24 + 9
Now combine like terms to get the final answer:
6x - 15
Answer:
x = 30

They are vertical angles.
Equation: 2x - 15 = 45
2x = 60
x = 30

Answer:
176.7 square feet
Step-by-step explanation:
Diameter, d = 15 feet
radius, r = d/2
r = 15/2 = 7.5 feet
π = 3.142
Area of the pool = area of a circle
= πr^2
= 3.142 * 7.5^2
= 176.7375
to the nearest tenth
= 176.7 square feet
