65 divided by 7 is approximently 9, and 25 divided by 7 is approximently 3, so 9 plus 3 is 12, so Gracie must wash 12 cars to earn enough money to save 25 and spend 65!

Let us assume the width of the rectangle = x
Then
The length of the rectangle = 2x
The perimeter of the rectangle = 24 inches
We know the formula of the perimeter of a rectangle is
Perimeter = 2 (length + Breadth)
24 = 2 (2x + x)
24 = 2 * 3x
24 = 6x
x = 24/6
= 4
So the width of the rectangle = 4 inches
length of the rectangle = 2x
= 2 * 4 inches
= 8 inches
Now
The Area of the rectangle = Width * Length
= 4 * 8 inches^2
= 32 inches ^2
So the area of the rectangle is 32 square inches. I hope i have helped you.
The answer is -12y i think in my opinion
Note that 49b^2 - 256 = 0 is the difference of two squares. Thus, 49b^2 - 256 = 0 can be re-written as
(7b)^2 - 16^2 = 0, which factors into (7b+16)(7b-16)=0.
Solving for b: 7b+16=0 becomes b = -16/7, and
7b-16=0 becomes b = 16/7.
As expected, this 2nd order equation has 2 solutions.
