Answer:
Zeros are the values of x that make the function equal zero. ie x2−8x+12=0. Factor the quadratic and solve for x.

Answer:
These two results are identical.
Step-by-step explanation:
Before we can compare these two expressions we need to perform the indicated multiplication.
The first expression is 9c + 2.
After the multiplication indicated, the second expression is 9c + 2.
These two results are identical. Yes, the two expressions ere equal.

Answer:
13.3 m
Step-by-step explanation:
Let d represent the length of the diagonal. Then the length of the rectangle is (d-2) and the width is (d-6). The area is the product of length and width, so is ...
A = LW
83 = (d -2)(d -6) = d² -8d +12
71 = d² -8d . . . . . . . . subtract 12 to get the constant out of the way
d² -8d +16 = 87 . . . . add (-8/2)² = 16 to both sides to complete the square
(d -4)² = 87 . . . . . . . write as a square
d -4 = √87 . . . . . . . positive square root
d = 4 +√87 ≈ 13.3 . . . . add 4
The diagonal is about 13.3 meters long.

<em>Additional comment</em>
If you check to see if the side lengths actually correspond to those of a rectangle, you find that they do not. <em>The geometry described here is impossible</em>. The rectangle with the proposed relations between sides and diagonal would have a diagonal of about 12.899 m and an area of about 75.19 m².
