What we know:
Perimeter=60
Perimeter formula=2l+2w
l=2w
This perimeter has the following set up using p=60 and l=2w:
perimeter =2(l)+2w
60=2(2w)+2w
60=4w+2w
60=6w
Now that we know how many w's we need to have we can use this information to find which equations have 6 w's and which one does not.
Look at the first equation:
2(2w+w)=60 distributive power
4w+2w=60 like terms
6w=60 correct
second equation:
w+2w+w+2w=60
6w=60 like terms, correct
third equation:
2w+2x2w=60 multiplication property
2w+4w=60 like terms
6w=60 correct
fourth equation:
w+2w=60 like terms
3w=60 not correct
Fourth equation is not correct.
Answer: You would share in exactly 55 squares.
Step-by-step explanation: To solve this, you need to know how to convert, divide, and multiply.
10*10=100
100/n=20
n=5
11*5=55
SO, you shade in 55 squares.
It's actually: I = PRT
I = Interest
P = Principle
R = Rate
T = Time
So for graphs, to tell if its a function is to see how many points are on the x-line for the coordinate. Functions will only have one point on each x-line.
With the top left, x = 0 has 2 points on it, so that is incorrect.
With top right, x = -1 has 2 points on it, so its incorrect as well.
Bottom left has 3 points on x = 0, so that's incorrect.
Bottom right, however, has no x-line where there are two or more points on it, so it is a function.
Answer:
f(4) = 0
Step-by-step explanation:
f(4) means what is the value of y when x = 4
Now x = 4 is on the x- axis, where y = 0, thus
f(4) = 0
