Answer:16 weeks
Step-by-step explanation:Since we know Sam can make 20 paintings in 4 weeks we must add the weeks
8 weeks will be 40 paintings
12 weeks will be 60 paintings
16 weeks will be 80 paintings
Hence the answer is 16 weeks to create 80 paintings
The answer is A, make sure to combine like terms
Angle B is 50 degrees, subtract 40 degrees from 90 because complementary means a total of 90
6x-(3)(8)x - 9
=6x+-24x+-9
=6x+-24x+-9
=(6x+-24x) +(9)
=-18x +-9 (answer)
