200 inches in 2 hours
200÷2= 100 inches in 1 hour
100 inches per hour divided by 50 inches = 1/2 hour
the snail will travel 50 inches in 1/2 hour
Answer:
1/3
Step-by-step explanation:
i/3 chance
Answer:
distribute -5 and -4
Step-by-step explanation:
-5(-6x-9y)-4(-10x+7y)
(30x + 45y) - (- 40x + 28)
30x + 45y + 40x - 28
45y + 70x - 28
The third quadrant are both negative numbers so the answer is B.
Answer: 9x + 4x²
Explanation:
1) Length = 14x - 3x² + 2y
2) Width = 5x - 7x² + 7y
3) Length - width = [14x - 3x² + 2y] - [5x - 7x² + 7y]
4) Calculate:
i) Distribute the negative sign in front of the second polynomial:
14x - 3x² + 2y - 5x + 7x² - 2y
ii) Combine like terms:
9x + 4x²
5) Answer: 9x + 4x²
