Answer:
x =(8-√176)/8=1-1/2√ 11 = -0.658
Step-by-step explanation:
In order to find the answer to this question, you have to use the distance formula in order to find the length of the triangle sides. Then you divide the length of the pre-image by the length of the image. The distance formula can be found here, it is very awkward to type it our so I will give you a helpful link: http://www.mathwarehouse.com/algebra/distance_formula/index.php
So the distance of PQ , which has a corresponding side of AB is about 4.
The distance of AB is about 14.
14/4 = 3.5 So the answer is D. 3.5
