Workers on the assembly line produce 4x + 6 boats each day. Which expression shows how many boats they produced in 12 days?

4x + 6 * 12

To determine how many boats were produced in 12 days, we can substitute the value 12 into the expression 4x + 6.

Therefore, the expression that shows how many boats were produced in 12 days is: 4(12) + 6.

Simplifying, we have: 48 + 6.

Adding, we find that the workers produced 54 boats in 12 days.

To find the number of boats produced in 12 days, we can substitute 12 for x in the expression 4x + 6.

So, substituting x with 12 in the expression 4x + 6:

4(12) + 6

Simplifying the expression:

48 + 6

Combining like terms:

54

Therefore, the expression that shows how many boats they produced in 12 days is 54.
