L = Length
W = Width
L x W = area
Length = 2w
Lets find the width by solving for w.
2w + w = 36
3w = 36
3w/3 = 36 / 3
w = 12
So
L = 2 x 12 = 24
W = 12
L X W = area
24 x 12 = 288 cm^2
X = 45.
Since opposite exterior angles are congruent, you can set the 2 values equal to each other. When you solve for x, you should get 45.
Every linear graph is just a straight line, so if there are any curves or unnatural shapes, than you know it is not linear. As for equations, if it can be shaped into y=mx+b where m and b are numbers, then it will be a linear equation.
1 mm

False
(5,5)
y < x + 3
5 < 5 + 3
5 < 8 (correct)
(5,5)
y > -2x - 1
5 > -2(5) - 1
5 > -10 - 1
5 > -11 (correct)
so (5,5) is a solution..and there are many more
