Question

Let n = 4, what is the value of 7 x 6 + n x 2? (A) 50 (B)92 (C)98 (D)140

Answer 1

Alright so we know that n = 4 so we just plug 4 where the n is.

7 × 6 + 4 × 2 

So the first thing you do is multiply 7 × 6 which gives you 42. Then you do the same for 4 × 2 which is 8.

After that you add 42 + 8 which gives you 50.
So your answer is A. 50

Hope that helped!

Answer 2

7 x 6 + 4 x 2
42 + 8
50
