Find the side lengths of each triangle.

14.) 8, 15.) 8.6

Step-by-step explanation: For number 14, all the side lengths are equal. Pick any two sides, we’ll choose z+5 and 3z-1. They are equal so you can set up the equation z+5=3z-1. Add 1 on both sides. Z+6=3z. Subtract z on both sides. 6=2z, z=3. Then plug it in. 3+5=8. So for the first triangle, the answer is 8. Then do the same thing for the second triangle. 2x+6.8=8x+1.4 Subtract 1.4 on both sides. 2x+5.4=8x. Subtract 2x on both sides. 5.4=6x. X=0.9. Plug 0.9 in. 0.9 times two + 6.8. The answer for the second one is 8.6

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]

i think it would be 42cm
