Answer:
P = 10x + 4
Step-by-step explanation:
Formula to find perimeter:
P = 2(l + w)
P = 2(2x + 3x + 2)
P = 2(5x + 2)
P = 10x + 4
Answer:
500 minutes
Step-by-step explanation:
Ok, so the first thing we want to do is figure out how long it takes to complete one lap.
So if it takes 10 minutes to travel 2 laps lets find out how many minutes for one.
It would be 5 minutes for one lap, if you divide 10 by 2 because of the 2 laps.
Next, you just multiply the 5 minutes by 100 laps:
This gives you 500 minutes.
Hope this helps :)
Answer:
f(x) = x + 2
Step-by-step explanation:
A linear function has the form
f(x) = mx + c
Evaluate f(0) = 2, that is
2 = m(0) + c
2 = 0 + c ⇒ c = 2
Evaluate f(2) = 4, that is
4 = 2m + c ← substitute c = 2
4 = 2m + 2 ( subtract 2 from both sides )
2 = 2m ( divide both sides by 2 )
1 = m
Hence
f(x) = x + 2 ← is a possible linear function
