D.) 18, 36, 54, 72, 90

Answer 1

Answer:

The algebraic expression is 12x+6

Let x=1

Now putting the value of x=1

12.1+6=18,

then putting the value of x=2,3,4 and 5 of the algebraic expression 12x+6

x=2

12.2+6=30,

x=3

12.3+6=42,

x=4

12.4+6=54,

x=5

12.5+6=60

the value of the expression are C.18,30,42,54,66.
