Segment ab measures 3 cm. point o is the center of dilation. how long is the image of ab after a dilation

The length of image AB after dilation is 3s cm.

Step-by-step explanation:

Let us consider the scale factor = s

The length of pre image = 3 cm

Therefore,

The length of the image AB after a dilation = 3  (s)

                                                                     = 3s cm

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
