Option b: 10 in, 18.5 in, 31.5 in.
Explanation:
The three sides of a triangle are
and 
The perimeter of the triangle is
.
Since, Perimeter = all sides of the triangle
Let us add all the three sides to determine the length of each side.

Substituting the value of Perimeter and simplifying, we get,

Substituting
in the three sides of the triangle
and
, we get,



Thus, the lengths of each side are 10 in, 18.5 in, 31.5 in.
The answer of this is x=0
The ordered pair would be (-5,8)
Kevin linear function is y = 3x + 1 while Jill function is y = 3x - 1
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Using the points (0, 1) and (2, 7), hence for Kevin:
y - 1 = [(7 - 1)/(2 - 0)](x - 0)
y = 3x + 1
Jill’s function has a y-intercept that is 2 less than the y-intercept, hence b = 1 - 2 = -1
Jill function is:
y = 3x - 1
Kevin linear function is y = 3x + 1 while Jill function is y = 3x - 1
