Select ALL of the appropriate names for the following figure.

A and B

Step-by-step explanation:

The image provided shows us a segment line. The solution to your problem is answer choice A and B. In A, we have CD and a segment line, which is correct as it is finite. In B, we have DC which is also correct since it is another way to write the line's name and also has a segment line. In C, it has a correct line name but is infinite to the right and means it is a ray line, the ray line does not correspond to our segment line shown in the image so therefore it is not correct. Finally, in D, we have been given again a correct name for the line, but because it is an infinite line then it is not correct.

The correct are the ones which are already selected as the symbol above CD and DC are the symbols of line segment.

In third DC, it shows ray while in last CD, it shows a line.

Hope this helps :)

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
