Answer:
Do you have the pictures? Otherwise I'm afraid I can't help you haha. Show me the pictures and I'll have you an explanation and answer :)
Step-by-step explanation:
We'd need more information like the relationship between those equations.
As we know,
Area of parallelogram :
Yes
If you add 87.84, 85, and 100 you get 272.84. Once you divide that by 3 you get 90.946, which would be your test average if you score 100 on your next test.
2c + 6 = 30
2c = 24
c = 12
