Let's use the distance formula:
So it is:
AB :
BC:
CA:
So 9.43 + 5 + 8 =22.43
Answer:
<em></em>
Step-by-step explanation:
Functions have independet variables(the value of the variable could be any number, we have no restrictions) and dependent variaariables(the values of this variables depends of idependent variables)
the problem says that <em>x</em> is the independent variable, so we say that <em>y</em> is a dependent variable. Dependent need to be replaced by funcion notation, in this case we use <em>y=f(x)</em>
So we raplace it in the equation and we have:
<em></em>
we solve for <em>f(x)</em> passing <em>-6x</em> and <em>-9</em> to the right side and changing the signs, and we get:
<em></em>
360 / # of sides = 180 -EACH interior angle
360 / (180 - EACH interior angle) = Number of sides
360 / (180 -162) = Number of Sides
360 / 18 = Number of Sides
Number of Sides = 20

This is the concept of combination. The number of letter-sequence that are possible to be formed from the letters q,u,a,k,e,s will be evaluated as follows:
Total number of letters is 6
Maximum number of letters in a word is 4
thus the number of four letter sequence that can be formed will be:
6C4
=15
The reason why we are using combination is because no letter can be used more than once in each sequence.
Explanation:
First, switch sides of an equation.
Then, you subtract by the 80 from both sides of an equation.
And finally, simplify and subtract the numbers.
Hope this helps!
Thank you!
Have a great day!
