Question

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

Answer 1

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)

Answer 2

Answer:

$27$

Step-by-step 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 :)
