C= 2sqrt55 or 14.83
formula= a^2+b^2=c^2
plug in
14^2+sqrt24^2=c^2
196+24=c^2
220=c^2
take the square root of each side
2sqrt55=c
Let's take l and w as the length and the width of the rectangle.
According to the given information the length is 3 less than twice the width:
And the area, which is the product of the length times the width is 14. Using the equation above, we can re write the formula for the area, this way:
Now, we have to solve the quadratic equation using the quadratic formula:
w has 2 values, but for this context, the logic value is 7/2. It means that the width of the rectangle is 7/2.
Now, we can use this value and the first equation to find the length:
The length of the rectangle is 4 and the width is 7/2.
Answer: -4xy + 2x
Step-by-step explanation:
4xy - 8xy = -4xy
4x - 2x = 2x
