A=1/2*h(20+8)
can you solve for h or the equation .

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

                     a-(1/2*h*(20+8))=0 

 3.1     Solve   a-14h  = 0 

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK). 

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  a-14h  = 0 and calculate its properties

Notice that when a = 0 the value of h is 0/-14 so this line "cuts" the h axis at h=-0.00000

When h = 0 the value of a is 0/1 Our line therefore "cuts" the a axis at a= 0.00000

Slope is defined as the change in h divided by the change in a. We note that for a=0, the value of h is 0.000 and for a=2.000, the value of h is 0.143. So, for a change of 2.000 in a (The change in a is sometimes referred to as "RUN") we get a change of 0.143 - 0.000 = 0.143 in h. (The change in h is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

answer: a.   one is a factor of every whole number since every number is divisible by itself.
