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

Answer:

$x=\frac{3}{4}=0.75$

Step-by-step 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 $x$)

$x=\frac{3}{4} =0.75$ (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!
