Answer:
x=3 e y=4
Step-by-step explanation:
x/2=6/y=27/18
...
x/2=27/18
18.x=2.(27)
18x=54
x=54/18
x= 3
...
6/y=27/18
27y=6.(18)
27y=108
y=108/27
y=4
Method OneYour calculator might be able to do this. Mine does it like this.
6
nCr
2
=
15
Method 2You could simply set up 6C2
This gives you
Method ThreeYou only have to do this a couple of times to see how the cancellation works.
After all the cancellation takes place you have
6*5/2 = 15
I truly don’t know the answer but i think it is 837 feet
Answer:
Step-by-step explanation:
we know that
The formula to calculate the area for a trapezoid is equal to
where
a and b are the parallel bases
h is the height of trapezoid
A is the area
<em>Solve for a</em>
That means ----> isolate the variable a
Multiply by 2 both sides to remove the fraction in the right side
Divide by h both sides
Subtract b both sides
