Question

If a=6 b=2 what is 2ab

Answer 1

Substitution method!
Replace letters with the numbers provided.
2ab becomes 2(6 x 2)

6 x 2 = 12
2(12)
2 x 12 = 24
24 is the answer!

Answer 2

Given a = 6 and b = 2, all we must do is multiply our values:

2ab becomes 2(6)(2).

2 • 6 = 12
12 • 2 = 24

Therefore, if a = 6 and b = 2, 2ab is equal to 24.
