It is quite simple actually since it is simple division with the negative rules.
Just simplify the problem and use the negatives to determine if it is positive or negative. (two negatives equal a positive and one negative equals a negative)
I think that you round to 9.80 seconds. Pardon me, I didn't understand the problem well
Answer:
-24a² - 42a - 28
Simplified form = 12a² + 21a + 14
Step-by-step explanation:
-4(7 + 3a) - 6a(4a - 5) (distribute -4)
-28 - 12a -6a(4a - 5) (distribute -6a)
-28 - 12a -24a² - 30a (collect like terms)
-24a² - 42a - 28
We can simplify
-24a² - 42a - 28 (divide -2)
12a² + 21a + 14
Hope this helps ya! Keep smiling!
