Question

Find the value of X. Please help ASAP!! I have no idea how to do this and I have to have it done soon!!

Answer 1

`x=(3)/(4)=0.75`

Explanation:

From the shape of the quadrilateral, we can assume that it is a parallelogram. In a parallelogram, opposite sides are congruent and thus have the same length.

In this case, we are given that two opposite sides have lengths of
`4x+5` and
`8`. Therefore, since the quantities must be equal, we can write the following equation to solve for
`x`:
`4x+5=8`. Solving for
`x`, we get:

`4x+5=8`

`4x=3` (Use the Subtraction Property of Equality to subtract
`5` from both sides of the equation, which isolates
`x`)

`x=(3)/(4) =0.75` (Use the Division Property of Equality to divide both sides of the equation by
`4` to get rid of
`x`'s coefficient)

Hope this helps!
