1st you would need to multiply 6 and 3 since n=3 which would give you 18. Then simply subtract 2 which would give you 16

The final answer is 16.

Answer:

Step-by-step explanation:

If $n = 3$ , just put the number $3$ instead of $n$ .

So:

$6n-2 = 6 * 3 - 2 = 18 - 2 = 16$

The perimeter of the picture frame is 38 inches. The width of the frame is 7 inches, what is the length?

o-na [289]

Answer:

12 inches

Step-by-step explanation:

So you know that the perimeter of a picture frame (a rectangle) is 2 widths plus 2 lengths.

Let x= lengths and w= widths

From the question we already know that w=7, so we can set up an equation that says:

2x + 2w = 38

2x + 2(7) = 38

2x+14 = 38

2x +14 -14 = 38-14

2x = 24

2x/2 = 24/2

x= 12

Since x= lengths =12

the length of the frame is 12 inches.
