Lines AB and CD are parallel. Using the given coordinates
The equation of line CD is
Given :
Lines AB and CD are parallel. The coordinates of point A are (-2,5), the coordinates of point B are (6,3),the coordinates of point D are (8,5)
When two lines are parallel then their slopes are equal
Lets find the slope of AB using the given points
A is (-2,5) and B is (6,3)
Find slope using slope formula
Slope of AB is
Slope of AB and CD are same
Slope of CD is
Now we find equation of line CD y=mx+b
Use point slope formula
use the given point D(8,5) and slope m
Substitute the values
The equation of line CD is

Area is a squared measure of the one-to-one measure of the figures. If the surface areas of the figures, from smaller to larger, are 36 and 49, by taking the square roots of those numbers, you get the perimeter measure of the figures, which is the one-to-one measure. The square root of 36 is 6, and the square root of 49 is 7. Now, in order to find the ratio of the volumes smaller to larger, we take that one-to-one measure and cube it, since volume is a cubed measure. We will set up the proportions to find the cubed measures first. My proportion will be set up with the smaller figure's info on top and the larger figure's info on bottom: . Those are the cubed ratios. Now we will set up our equation to solve for the volume of the larger:
. Now we can cross-multiply to solve for x, the volume of the larger figure. 216x = 222264. Dividing both sides by 216 gives us a volume for the larger figure of 1029 inches cubed. There you go!
