Let
be the dimensions of the rectangle. If the original perimeter is 52, we deduce that

Doubling the width and increasing the length by 17 leads to a new perimeter of

From the first equation, we know that (for example) 
Plug this in the second equation to get

So, the original length was 21, which implies that the original width was

X^3+x^2-4x-4
x^2•(x+1)-4(x+1)
(x+1)•(x^2-4)
= (x+1)•(x-2)•(x+2)
Step-by-step explanation:
given,
x² + y² = 40
2xy = 24
(x + y)² = x² + 2xy + y²
so,
40 + 24 = 64
therefore option C is correct

The coordinate for point P which is one-third the length of the line segment from a to b is (-4, -5)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Point a is at (-8, -13) and point b is at (4, 11). Hence the coordinates for point p(x, y) which is one-third the length of the line segment from a to b is:
