Answer:
11.
Take out 2x ( greatest common factor )
Factor
Don't forget about the 2x we took out earlier
Solution to 11:
12.
This is the difference of squares, so let's use the formula...
if, and
then, the Solution to 12 is:
13.
First of all, you must find the greatest common factor because there isn't anything else you can do.
Now you can see the difference of cubes...
so, the Solution to 13 is:
Add/subtract likenesses here (only one though)
4,000,000
400,000
00,000
8,000
700
30
0
12.50+0.40e=14.75+0.25e
-12.50 -12.50 Subtract 12.50 to elimanate on the right side to isolate e
0.40e=2.25+0.25e left from subtracting 12/50
-0.25 -0.25e subtract 0.25e to put e on one side.
0.15e=2.25 left from subtracting 0.25 e
0.15e/0.15=2.25/0.15 divide to isolate e and to get you're answer
e=15
Hope it helps!
Answer:
7:24 pm
Step-by-step explanation:
speed = distance/time
time * speed = distance
time = distance/speed
time = (195 miles)/(50 miles/hour)
time = 3.9 hours
The trip will take 3.9 hours.
3 hours + 0.9 hours = 3 hours + 0.9 hours * 60 minutes/hour =
= 3 hours + 54 minutes
The trip will take 3 hours and 54 minutes.
3:30 pm + 3:54 = 6:84 pm = 7:24 pm
Answer: 7:24 pm
