The example I would be using is the level of a see-saw and take
a point 1 /x of the way amid the middle and the left end. If you change
the point vertically by f feet, the far right finish transfers vertically
by f×−x feet. If you push down, f would be negative then you are
multiplying two negative numbers for a positive result, this means that the
other end moves up.

Step-by-step explanation:
A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0
B) Since the discriminant is 0, this means the equation only has one root.
C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)

Answer:
175.929188601
Step-by-step explanation:
Answer:
Option A.
Step-by-step explanation:
From the figure attached,
Given : ΔABC ~ ΔDEC
By the property of similarity,
"Corresponding sides of the similar triangles are proportional"

Since, 

6x = 42(32 - x)
6x = 1344 - 42x
6x + 42x = 1344
48x = 1344
x = 
x = 28 units
Therefore, Option (A). x = 28 units will be the answer.
