The perimeter of the triangular park shown on the right is 13. 1. What is the missing length? The missing longth is (Simplify your answer.)

Missing side = 30

Step-by-step explanation:

13x - 1 = x - 1 +4x + 4

13x - 1 = 5x - 3

8x = 2

x = 4

Replace (x - 1) and (4x +4) with the x that we just found.  It should equal 3 and 20. Then replace the x in (13x - 1). It should equal 53. Then subtract 53 - 23.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
