Lewis needed to find the difference in lengths between the hypotenuse and the longest leg of this triangle. His work is shown be

low. Triangle A B C. Side B C is 16 and side A C is 12. Hypotenuse A B is labeled c. 12 squared + 16 squared = c squared. 144 + 256 = c squared. 400 = c squared. StartRoot 400 EndRoot = c. 200 = c. Difference: 200 minus 12 = 188. What errors did Lewis make? Check all that apply. He simplified StartRoot 400 EndRoot incorrectly. It should be 20 instead of 200. He found the difference between the hypotenuse and the short leg instead of the long leg. He evaluated 12 squared incorrectly. It should be 12 (2) = 24. He evaluated 16 squared incorrectly. It should be 16 (2) = 32. He should not have taken the square root of each side to get rid of the exponent.

Show answer in lowest terms. 25/75+ 25/125=
Anit [1.1K]
Hi Jujub! To find the answer in lowest terms, first you have to find the lowest common denominator. To find this, find the lowest common multiple of 75 and 125, which is 375. Now, to make the common denominator, you have to make equivalent fractions. 375 ÷ 75 = 5, and 5 × 25 = 125. So the new fraction is 125/375.  Now the same thing for 25/125.  375 ÷ 125 = 3, and 3 × 25 is 75. So the new fraction is 75/375.  Now add the new fractions:  
125/375 + 75/375 =  200/375

This answer can be simplified to 8/15.
