Question

Which expression represents, six times a number plus 8 times a number?

6a + 8

6 + 8 + a + b

48(ab)

6a + 8b

Answer 1

6a+8b; when a variable is next to a coefficient then that means they are multiplying each other, we just don't know what a or b is.

Answer 2

The answer is 6a+8b, so *D*, hope it helps!
