es per hour while the other travels80 at miles per hour. how long will it take for the two trains to meet?
1 answer:
Let's use the variable n for time (in hours)
70n + 80n = 270
150n = 270
n = 1.8
It will take 1.8 hours, or 1 hour and 48 minutes

Answer:
<u>Width = 7 inches</u>
<u>Length = 23 inches</u>
Step-by-step explanation:
Let :
Equating to area :
- (2x + 9)(x) = 161
- 2x² + 9x = 161
- 2x² + 9x - 161 = 0
- 2x² - 14x + 23x - 161 = 0
- 2x(x - 7) + 23(x - 7) = 0
- x - 7 = 0
- x = 7
Dimensions are :
- <u>Width = 7 inches</u>
- Length = 2(7) + 9
- <u>Length = 23 inches</u>
