W= width
l= 4w-13

Perimeter= 2l+2w
Substitute (4w-13) for l

174=2(4w-13)+2w
174=8w-26+2w
174=10w-26
Add 26 to both sides
200=10w
Divide both sides by 10
20 inches= w

Substitute the answer to find length.
l=4w-13
l=4(20)-13
l=80-13
l=67 inches

Check:
174= 2(67)+2(20)
174=134+40
174=174

Hope this helps! :)

If you would like to solve 24% of what number is 12, you can do this using the following steps:

24% of what number is 12
24% of x is 12
24% * x = 12
24/100 * x = 12    /*100/24
x = 12 * 100 / 24
x = 50

Result: 24% of 50 is 12.

Answer:

  area = x(3x +10)

Step-by-step explanation:

The lengths of the unmarked sides are found as the difference between the lengths of the parallel marked sides.

  horizontal unmarked = (2x+15) -x = x +15

  vertical unmarked = (2x -5) -(x -5) = x

The area of the figure is the sum of the areas of parts of the figure. The area can be divided several ways. One is shown in the attachment, along with the areas of the parts and of the whole.

The whole area is ...

  x(2x -5) +x(x +15) = x((2x -5) +(x +15)) = x(2x -5 +x +15) = x(3x +10)
