Answer:
2(4a - 4b) + 4(3a + 2b) = 20a
Step-by-step explanation:
2(4a - 4b) + 4(3a + 2b)
8a - 8b + 12a + 8b
8a + 12b - 8b + 8b
20a+ 0 = 20a
Thus, 2(4a - 4b) + 4(3a + 2b) = 20a

Answer: 46 degrees
Step-by-step explanation: First you need to find the value of the vertical angle which is 180-(85+53) which is 42 degrees. Since vertical angles are congruent, you can say that 180-(42+92) is equal to x. When you solve it, you get x=46 which is your answer
