Answer:
3x^ - 4x - 76
Step-by-step explanation:
I would start like this: which year was the seventh AMC 8??
the first was in 1985
The second: 1986
3: 1987
4: 1988
5: 1989
6: 1990
7: 1991
so seventh AMC 8 took place in 1991.
she was then 12, so we can subtract this age from 1991:
1991-12=1979
so she was born in 1979!
3×5 is 15
