He's driving 42mph. 42m/60h=0.7mpm. 12 minutes x 0.7 mile per minute= 8.4 miles. 21-8.4=12.6 miles left . 12.6 x 0.7= 8.86 minutes left or about nine
Answer: See the picture attached.
Step-by-step explanation:
A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.
When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".
When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".
In this case we know that the scale factor is:

Since:

It is a Reduction.
You can identify that the vertices of the quadritaleral are:

So you need to multiply the coordinates of eac vertex by
in order to get the coordinates of the image.
Then, you get:

Now you can plot the points and draw the image of the given quadrilateral.
See the picture attached.
