2x + 7 - 10

Or it also could be (2x + 7) - 10 but the parenthesis aren't really needed

r:c

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

$\frac{RQ}{CB}=\frac{RP}{CA}=\frac{PQ}{AB}$

substitute the given values

$\frac{p}{a}=\frac{q}{b}=\frac{r}{c}$

therefore

$\frac{p}{a}=\frac{r}{c}$

p:a=r:c
