The length is two inches less than five times the width. This means
Length (L) = 5w - 2. (Does this make sense? You calculate 5 times the width and then minus 2)
Then we know the perimeter of a rectangle is 2(L+w) so
Perimeter = 2(5w-2 + w) = 2(6w-2) = 12w - 4 (so C and D are both correct because they are equal)
We check the other two options manually,
A: 2(5w-2)+2w = 10w-4+2w = 12w - 4 (so A is correct because it equals D which also equals C)
B: w+w+5w+5w-2 = 12w - 2 (which does not equal any of the other options)
So correct answers are A, C and D because they are all equal.
The answer is a I believe
I think it would -4 + 6n to the power of 3 - 2n to the power of 2. I could be wrong. If so, you can report it as an error or something.
Answer:
Answer (a):
distance traveled per revolution = 1.5 feet
Answer (b):
slope = 1.5 feet per revolution
Step-by-step explanation:
We have been given a graph which shows number of revolutions v/s distance traveled in feet.
Answer (a):
Now we need to find about how far does Miguel travel per revolution. That means find distance traveled in 1 revolution.
From graph we see that 10 revolution corresponds to 15 feet.
then 1 revolution = 15/10 = 1.5 feet
hence final answer is 1.5 feet.
Answer (b):
slope means [change in y-value] / [change in x-value]
From graph we see that 10 revolution corresponds to 15 feet.
then slope = 15/10 = 1.5 feet per revolution
