I hope this is right
Radius = 4 yards
Area = PI * radius^2
Area = 3.14 * 16
Area = 50.24 square yards
Answer:
x = -1 or x = -y
Step-by-step explanation:
Solve for x:
(x + 1) (x^2 + 2 x y + y^2) = 0
Split into two equations:
x + 1 = 0 or x^2 + 2 x y + y^2 = 0
Subtract 1 from both sides:
x = -1 or x^2 + 2 x y + y^2 = 0
Write the left hand side as a square:
x = -1 or (x + y)^2 = 0
Take the square root of both sides:
x = -1 or x + y = 0
Subtract y from both sides:
Answer: x = -1 or x = -y
The answer is 35. All you have to do is multiply them together.
