Answer:
<h2>20 cm.</h2>
Step-by-step explanation:
We know that the permiter is defined as
Where 
is the longest side, 
is the smallest and 
is the middle side.
If 
then, 
, where we need to find an expression for using the law of cosines.
Replacing all expression, the perimeter is
Using a calculator, the perimeter is 20 units centimeters.
The correct answer is 24
You have to apply factorials here and formulas. You have 4 letters which means that your n=4, and you have 3 objects at a time which, means that you have 4 different groups of combinations with 6 permutations in each due to the 3! factorial. 6 x 4 is 24.
LCM stands for Least Common Multiple.
The LCM of two numbers is the lowest number that can divide into the two original numbers.
For most numbers, you can find the LCM by simply multiplying the two numbers:
The LCM of 7 and 13 will be 91.
Answer: B. f(x)=(x+4)(x-2)^2(x+3)
Step-by-step explanation:
in the graph there's two negative x value and one positive x value
so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)
the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))
