Answer:

3p-q-2

Step-by-step explanation:

Since all three sides add up to 6p+2q-5

p-3+2p+3q+x=6p+2q-5

3p+3q-3+x=6p-2q-5

x=3p-q-2

Answer:

3p-q-2

Step-by-step explanation:

6p+2q-5 = Perimeter

6p+2q-5= (p-3) + (2p+3q) + ?

Subtract (p-3) from both sides:

(6p+2q-5) -(p-3) = (2p+3q) + ?

Subtract (2p+3q) from both sides:

(6p+2q-5) -(p-3) -(2p+3q) = ?

Simplify:

6p+2q-5-p+3-2p-3q

3p-q-2

Therfore the missing length is 3p-q-2 in simplest expression form.
