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
Answer:
Number of months= 12 months
Step-by-step explanation:
Giving the following information:
One time fee= $20
Monthly fee= $7.5
Total cost= $115
<u>To calculate the number of months, we need to use the following formula:</u>
<u></u>
Number of months= (total cost - one time fee) / monthly fee
Number of months= (115 - 20) / 7.5
Number of months= 12.67
Number of months= 12 months
