Answer: LHS = RHS

Step-by-step explanation:

Heya!!

Here, we need to compare the LHS and RHS

So, here is the solution -

(9p-5q)²+ 180 pq = (9p+5q)

LHS

= (9p-5q)²+ 180 pq

= 81 p² + 25 q² + 90 pq + 180 pq

= (9p - 5q) ²

RHS = (9p - 5q) ²

Hence, proved => LHS = RHS

Hope it helps!

Answer:

5 : 9

Step-by-step explanation:

9p = 5q ( divide both sides by q )

9 × \frac{p}{q} = 5 ( divide both sides by 9 )

\frac{p}{q} = \frac{5}{9} , that is p : q = 5 : 9
