Answer:
6.8x - 5
Step-by-step explanation:
To answer this question I combined like terms:
(2.5x + 4.3x) - 5
2.5x + 4.3x = 6.8x
Then you add the 5 to the end of the expression:
6.8x - 5
W - width
l - length
p - perimeter
The perimeter is 72 cm (p=72).
The length is twice the width (l=2w).
The formula for perimeter is 2w+2l=P.

Check the answer:

The length of the photo is 24 cm, the width of the photo is 12 cm.
(x+1)-(-2x-5)
=x+1+2x+5
=3x+6
=3(x+2)
