The point c (x, y) is in quadrant i. It is the vertex of a triangle. You reflect the triangle over the x-axis, then you dilate the triangle by the scale factor 2,Select an ordered pair that could be the coordinate of C" after the motion has been described

Step-by-step explanation:

Given

First, reflect over x-axis

The transformation rule for reflection over the x-axis is:

So:

Next, dilate by 2

The transformation rule for dilation is: k(x,y)

Where

So:

the answers c

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
