ABCD is a parallelogram. If AB = 3x and CD = x+10, find AB

Readme [11.4K]

A parallelogram by definition is a four-sided figure with opposite sides that are parallel.

If that's the case, the length of opposite sides should be the same as well, meaning that:

$AB=CD$

then,

$\begin{gathered} 3x=x+10 \\ \text{solve for x} \\ 3x-x=10 \\ 2x=10 \\ x=\frac{10}{2} \\ x=5 \end{gathered}$

find AB

$\begin{gathered} AB=3x \\ AB=3\cdot5 \\ AB=15 \end{gathered}$

Answer:

$\frac{ {x}^{2} + - 4x - 2 }{ {x}^{2} - 4 } + \frac{8x + 6}{{x}^{2} - 4} \\ = \frac{ {x}^{2} + - 4x + 8x - 2 + 6 }{ {x}^{2} - 4 } \\ = \frac{ {x}^{2} + 4x + 4 }{ {x}^{2} - 4 } \\ = \frac{ {(x + 2)}^{2} }{(x - 2)(x + 2)} \\ = \frac{x + 2}{x - 2}$
