Answer:
Sum is - 5n² -8n + 4.
Step-by-step explanation:
Given : (3n² – 5n + 6) + (–8n²– 3n – 2) .
To find : Sum .
Solution : We have (3n² – 5n + 6) + (–8n²– 3n – 2) .
Combine like terms :
(3n² - 8n²– 5n - 3n + 6 - 2).
- 5n² -8n + 4.
Therefore, Sum is - 5n² -8n + 4.
Okay so input would be at 1 and the output at 2.5, making the answer B.(If you're on plato) :D
Answer:
Parker ran 2.76 miles
Step-by-step explanation:
distance = speed x time
First, we have to convert 27 minutes and 39 seconds to minutes only we do this with 39/60 because then the seconds divide by total seconds and we can use it as a decimal
39/60 = .65
So it took 27.65 total minutes now we must convert it to hours, so that the 6 MILES per hour has matching terms, we do this by dividing 27.65 by 60 (theres 60 total minutes in an hour)
So it took 0.460833333 hours at a 6 mph pace, we can round this to 0.46
Now we can plug in the time and speed
Distance = 6mph x 0.46 hours
Distance = 2.76 miles
The lenght on the top on B. The length is 2 times more tan on sandbox 1.
The measure of VW from the given expressions is 4
<h3>Line segments</h3>
If the point V is on the line Uw, then;
UW = UV + VW
Given the following
VW=x, UV=3x-1 and UW=5x-5
Substitute
5x - 5 = 3x-1+x
5x - 5 = 4x - 1
Collect like terms
x = -1 + 5
x = 4
VW = x = 4
Hence the measure of VW from the given expressions is 4
