Since there are 2 congruent angles that means that you can set up the equation to equal to 180. 7x+8+7x+8+7x=180, 21x+16=180, 21x=164, x=7.81

Is 4(4a+20b) equivalent to 16a+24b

8090 [49]

No.

When you are distributing, you are multiplying to each monomial

4(4a) = 16a

4(20b) = 80b

16a + 80b is your actual answer
