Question

If p • q = 2p + q, then 2 • 3 is:A. 5B. 7C. 8D. 9

Answer 1

Given that

`p.q=2p+q`

Then,

`2.3\text{ is}`

Concept: In this case, the value of p is

`p=2`

The value of q is

`q=3`

Substitute the value of p = 2 and q = 3 in the expression below

`p.q=2p+q`

By substituting, we will have

`\begin{gathered} p.q=2p+q \\ p.q=2(2)+3 \\ p.q=4+3 \\ p.q=7 \end{gathered}`

Hence,

The final answer is OPTION B
