X = 3 and x = -1 are the answers for both. They are exactly the same equation.
FOR COMPLETING THE SQUARE
Make in terms of ()^2 which you can do by adding numbers to both sides. Eventually it will look like this:
(2x - 1)^2 - 7 = 0
Add to both sides, take a square root and then solve.
USE THE QUADRATIC FORMULA
Be sure to solve for zero and be aware of negatives when plugging in.
If you multiplied 12 and 30 you would get 360 minutes which is 6 hours. So if Janet lit a 12 inch candle and every 30 minutes it lost an inch it would take 6 hours. The reason being it loses an inch every 30 minutes and it has 12 inches.
I am not sure about this question because im in middle school but still tried it so....
300%/100=3
$6.00/3=$2.00
Before the markup the cotton candy cost $2.00
Answer:
a. 
b. 
c. They are equivalent
Step-by-step explanation:
a. The trapezoid can be divided into two triangles and one rectangle. For the three figures, the height is 12ft. For the rectangle, the dimensions are 12ftx10ft. Since the legs are of the same length the triangles have a base of 9ft (because the rectangle takes 10 feet from the base of 28 feet and there are 18 feet left over, these 18 are divided equally between the two triangles).



b. The formula is

c. They are equivalent
