The answer would be A) $79.20
(220*.4).9 as 60 percent off means that the product is only 40 percent of its original value, furthermore, we multiply the entire thing by .9
Latus rectum is the line segment that passes through the focus, is perpendicular to the axis, and has both endpoints on the curve.

Answer:
12 m
Step-by-step explanation:
Given that the design, ABCD, was dilated to get a photocopy, EFGH, a scale factor or ratio was multiplied by the original lengths of the design to get the new measurement of the photocopy.
Thus, we are given the ratio, CD:GH = 2:3.
This means, any of the corresponding lengths of both figures would be in that same ratio.
Using the ratio of the design to the photocopy, 2:3, we can find the length of side EH of the photocopy.
The corresponding side of EH in the design is AD = 8m. Thus, AD to EH = ⅔


Cross multiply


Divide both sides by 2 to make EH the subject of formula


The length of side EH = 12 m
X - 65 - 4x.
3x - 65.
I assume that you subtract x times four (a number, x, multiplied by 4) FROM the difference of x and 65 (the same number and 65).
Hope this helps!
