Answer: The same trip will require 3.8 hours.
Step-by-step explanation:
Since we have given that
Time = ![4\dfrac{1}{2}=\dfrac{9}{2}](https://tex.z-dn.net/?f=4%5Cdfrac%7B1%7D%7B2%7D%3D%5Cdfrac%7B9%7D%7B2%7D)
Speed = 55 mph
So, distance would be
![Speed\times time=55\times 4.5=247.5\ miles](https://tex.z-dn.net/?f=Speed%5Ctimes%20time%3D55%5Ctimes%204.5%3D247.5%5C%20miles)
If the speed limit = 65 mph
So, time will be
![\dfrac{247.5}{65}=3.8\ hours](https://tex.z-dn.net/?f=%5Cdfrac%7B247.5%7D%7B65%7D%3D3.8%5C%20hours)
Hence, the same trip will require 3.8 hours.
The first one is 2x+y=-1
the second one is 13x+2y-1=0
Answer: x² - x - 12
Step-by-step explanation: When multiplying two binomials together, we can use the F.O.I.L. method.
<em>First, Outer, Inner, Last</em>.
We take the product of the first terms which is x² plus the product of the outer terms which is -4x plus the product of the inner terms which is 3x plus the product of the last terms which is -12.
So we have x² - 4x + 3x - 12.
Simplifying from here by combing the middle terms, we have x² - x - 12.
Pay very close attention to your positives and negatives as you F.O.I.L. because this is the area where most mistakes occur.
