Answer:
y = 12x-15
Step-by-step explanation:
The equation of a line is given by :

Where
m is slope and c is y-intecept.
Here, the slope is 12 and y-intercept is -15.
Then the equation is :
y = 12x+(-15)
or
y = 12x-15
Hence, the required equation for the line is "y=12x-15".
We know that the smaller base is x cm, the greater base is x+4 cm, and that the height is x/2 cm.
Since the area of a trapezium is given by

If we plug the expressions we have

If this must equal 84, we can solve for x as follows: start with

Multiply both sides by 4:

Subtract 336 from both sides:

We can divide both sides by 2 to make computation simpler:

Use the quadratic formula (or any mean you prefer) to solve this equation and get the solutions

We can't accept the negative solution, because it would imply

and we can't have negative side lengths. So, the answer is 12.
