Sorry I am stupid but I need help
nikklg [1K]

I believe the answer to your question is the first choice.

Since we have two sides that are 24 mm that means that the equation needs to have 2(24 mm).

And since we have 4 sides that are 18 mm, it means that the equation needs to have 4(18 mm).

so we get: P= 4(18 mm) + 2(24 mm)


Hope this helped and plz mark as brainliest!

Workers on the assembly line produce 4x + 6 boats each day. Which expression shows how many boats they produced in 12 days?
Annette [7]
We're going to assume that x = # of days.
Plug 12 in as x:
4 × 12 = 48
48 + 6 = 54
They produced 54 boats in 12 days.

A 13?-foot board is cut into two pieces. The longer piece is 7.5 feet longer than the shorter piece. What is the length of each?
chubhunter [2.5K]

Answer:

The smaller board would be 2.75 feet and the longer one would be 10.25 feet.

Step-by-step explanation:

In order to find this, assume the shorter board is equal to x. Next, we would know that the longer board would be equal to x + 7.5. Using these two assumptions, we can add the lengths together, set equal to 13 and then solve for x.

x + (x + 7.5) = 13

2x + 7.5 = 13

2x = 5.5

x = 2.75

Now that we have the length of the shorter board, we can add 7.5 to it to get the larger one.

2.75 + 7.5 = 10.25
