Answer:

x = 0,  x = 7

Step-by-step explanation:

Given equation:

\implies \dfrac{x+3}{x-3}+\dfrac{x}{x-5}=\dfrac{x+5}{x-5}

Multiply by (x - 5):

\implies \dfrac{(x+3)(x-5)}{x-3}+\dfrac{x(x-5)}{x-5}=\dfrac{(x+5)(x-5)}{x-5}

Factor out common term (x - 5):

\implies \dfrac{(x+3)(x-5)}{x-3}+x=x+5

Multiply by (x - 3):

\implies \dfrac{(x+3)(x-5)(x-3)}{x-3}+x(x-3)=(x+5)(x-3)

Factor out common term (x - 3):

\implies (x+3)(x-5)+x(x-3)=(x+5)(x-3)

Expand brackets:

\implies x^2-5x+3x-15+x^2-3x=x^2-3x+5x-15

Combine like terms:

\implies 2x^2-5x-15=x^2+2x-15

Simplify:

\implies x^2-7x=0

Factor and solve:

\implies x(x-7)=0

\implies x=0,7

What is the width of this shape
77julia77 [94]
We see that the area is 159 3/8 and the length is 18 3/4.

Because the area is the length*width, to find the width, we must divide the area by the length.

Think of it this way:
A = l*w

Divide l on both sides:
\frac{A}{l} = w

And w is what we're looking for.
So, divide 159 3/8 by 18 3/4. 

You should get that the width is 8.5 feet :)
