There are 12 inches in 1 foot. You know that the area of a square is or base times hight. A square has the same base and height. So we can say (base)^2. If the base is 12 inches in this case 12^2 = 144. Answer: 144 square inches.
Step-by-step explanation:
(x+2y)(x-2y)
- x^2-2xy+2xy-(2y)^2
- x^2-4y^2
I think you're having trouble because the equation you wrote for 8a has a slight typo.
The question says that the length is 9 less than twice the width. Your equation states the length is 9 times the width minus 2. So the length actually equals 2w – 9, meaning that w(2w – 9) = 180
Hope this helps! If you're still having trouble, let me know :)
Answer:
It is not a function because both (2,2) and (2,-2) have the same x-coordinate.
Step-by-step explanation:
To be a function for the same x value there should NOT be two different y values.
So, in (2, 2) and (2,-2)
For the same x value 2, there are two different y values 2, -2.
So, this is not a function.
