The figure shows two parallel lines AB and DE cut by the transversals AE and BD: AB and DE are parallel lines, and AE and BD are transversals. The transversals intersect at C. Angle CAB is labeled 1, angle ABC is labeled 2, angle ACB is labeled 3, angle ACE is labeled 4, angle CDE is labeled 6, and angle CED is labeled 5. Which statement best explains the relationship between Triangle ABC and Triangle EDC ? Triangle ABC is similar to triangle EDC , because m∠2 = m∠6 and m∠1 = m∠5 Triangle ABC is similar to triangle EDC , because m∠3 = m∠6 and m∠1 = m∠4 Triangle ABC is congruent to triangle EDC , because m∠3 = m∠4 and m∠1 = m∠5 Triangle ABC is congruent to triangle EDC , because m∠3 = m∠6 and m∠1 = m∠4

Randy is checking to determine if the expressions 2x+2+4x and 2(3x+1) are equivalent. When x=3, he correctly finds that both expressions have a value of 20. When x=2, he correctly evaluates the first expression to find that 2x+2+4x=14.What is the value of the second expression when x=2 and are the two expressions equivalent?A. The value of the second expression is 7, so the expressions are not equivalent.B. The value of the second expression is 12, so the expressions are not equivalent.C. The value of the second expression is 14, so the expressions are equivalent.D. The value of the second expression is 20, so the expressions are equivalent.

n cold climate areas, trucks are used to disperse salt on the roads in order to de-ice the roads, making them safe for travel. In some cases, cone- shaped sheds store the salt during the off-season, or until the roads need to be de-iced. This large salt storage shed sits 12 feet above the ground and holds approximately 51.4 cubic feet of salt. To the nearest hundredth of a foot, what is the radius of the large storage shed? Use 3.14 for . In your final answer, include all of your calculations.

The Truth About Antibacterial SoapAccording to Discovery Fit & Health, about 75 percent of liquid soaps claim to be antibacterial. While this kind of soap sounds like a good idea, it is really not more effective than regular soap. Soap in general works by binding with dirt and grime and bacteria. This binding action allows the particles to be washed away easily. Antibacterial soap really does no more than regular soap. In fact, to be more effective than regular soap, antibacterial soap should stay on your skin for about two minutes to do what it claims it can do. Most people do not wash their hands that long. In addition, antibacterial soap may do harm. First it kills both beneficial and harmful bacteria. Second, scientists believe bacteria may become resistant to antibacterial agents over time, especially if they are not used correctly. Finally, antibacterial soap does nothing to viruses. Most of the time, we get sick from viruses, not bacteria. In sum, antibacterial soap does not live up to the hype. You are better off just using regular soap.Works Cited Is Antibacterial Soap Any Better than Regular Soap?http://health.howstuffworks.com/skin-care/cleansing/myths/question692.htmHow is "The Truth About Antibacterial Soap" organized?
