Question

pq+qr+pr=2p+2q+2r
it true

Answer 1

Answer:

No, it is not true.

Step-by-step explanation:

Let us assume that p=1, q=2 and r=3

In case 1,

pq+qr+pr

After substituting, it is (1*2)+(2*3)+(3*1) = 2+6+1 = 9

In case 2,

2p+2q+2r

After substituting, it is (1*2)+(2*2)+(3*2) = 2+4+6 = 12

9 is not equal to 12.

Answer of both equations is not equal.

Therefore, pq+qr+pr is not equal to 2p+2q+2r.
