A dilation has a scale of 4. This describes an EXPANSION type of dilation.
The scale of 4 means that the dilated image is 4 times bigger than the original image. The dilated image still retained the same proportion of the original image even though it is in a larger scale.
Right answer is B. If we have f equal the amount of her remaining way so f it will be the difference between the way she has gone and her finish line. So we have 70 in the approximate middle of her way and F is between 70 feet and 105 feet, so 105=70+F
None. They're all acute angles.
I think the Answer is 64 !!!
Factor 8x+16
It would be 4(2+4x)
So the student made a mistake in step 2
It should be 4(2)+4(4x)
Answer C
