Answer:
The answer to your question is the third option
Step-by-step explanation:
Polynomial (5a - 3b² - a) + (b - 5 + 8a²)
1.- Group like terms
(8a²) + (5a - a) + (-3b²) + (b) + (-5)
2.- Simplify
8a² + 4a - 3b² + b - 5
3.- Order the polynomial
Result 8a² - 3b² + 4a + b - 5
Answer:
40,000,000
Step-by-step explanation:
If you look at the 10 millionth place by itself, it's just 38. Now look at 8 by itself. Remember this rule: 1-4 round down, 5-9 go to town. Since 8 is in the range of 5-9, round up. Look at 38 again. The nearest 10th would be 40, hence 40,000,000 as the answer.
4y⁴ - 8y³ - (5y³ + 6y + 3y⁴)
= 4y⁴ - 8y³ - 5y³ - 6y - 3y⁴
= (4y⁴ - 3y⁴) + (- 8y³ - 5y³) - 6y
= y⁴ - 13y³ - 6y
Answer: y⁴ - 13y³ - 6y
Answer:
6 round trip visits
Step-by-step explanation:
25 min drive to the store + 3 min to walk in the store + 3 min to walk back to car + 25 min to drive home = 56 total minutes for one round trip.
5 hours and 36 minutes = (5x60)+36 minutes=336 minutes
336 minutes/56 min per trip = 6 round trips
