The perimeter is the total of the length • 2, + Width • 2. Doing it in reverse order, 230 - 2(Width) = 104.
104/2 = 52
We can find slope by using (y1-y2)/(x1-x2).
(-8-4)/(14+2) = -0.75
Now put it in point slope form:
y-y1=m(x-x1)
y+8=-0.75(x-14)
Simply
y = -0.75x -18.5
The median is the middle number which is 21
Do not expand the brackets, divide both sides by -2 and reverse the inequality!
So x + 6 < -41/-2 = 20.5
Now subtract 6 from both sides
x < 14.5
Graph by drawing a circle at 14.5 and an arrow from the circle pointing left.
The solution set is all real numbers up to, but not including, 14.5
The answer to the question is C.
