Question

Plsss help!!!!!!!!!!!!!!!!!

Answer 1

`27`

Explanation:

A rhombus is a quadrilateral where all sides are equal in length. This means that
`\overline R \overline O = \overline O \overline C`.

From this, we can write:

`2x-15=x+6`

`x-15=6`

`x=21`

Now that we have solved for
`x`, we can find the length of
`\overline R \overline O` by using substitution:

`2x-15=2(21)-15`

`=42-15`

`=27`

Hope this helps :)

Answer 2

2x - 15 = x + 6
+ 15 +15

2x = x + 21
-x -x

x = 21

plug it into the problem again

2(21) - 15

42 - 15 = 27 (i think lol)
