Question

find the perimeter of the figure below, in centimeters.
(note: diagram is not to scale)

15.) write an expression that represents the perimeter of the figure below. write your answer in simplified form.

16.) rewrite in simplest terms: \\((-x + 5) + (-7x - 8)\\)

17.) rewrite in simplest terms:
\\(-4(-3t - 10t - 7) - t\\)

18.) find the value of \\(x\\) in the equation below.
\\14 = x - 12\\

19.) find the value of \\(x\\) in the equation below.
\\1 + x = 20\\

20.) solve for \\(t\\).
\\-2 + t = 1\\
