Answer: 19.8 Units
Step-by-step explanation:
The triangle is shown in the attached figure, and have three vertices:
,
and
.
Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.
In this sense, the modulus
is calculated as shown:

Hence, for each vector:



Now, the perimeter of a triangle is the sum of its three sides:

Finally:

Answer:
Lm
Step-by-step explanation:
average = (sum of numbers)/(number of numbers)
Solve the equation for "sum of numbers":
sum of numbers = average * number of numbers
sum of numbers = m * L
sum of numbers = Lm
Answer: B) Lm
Answer:
< (less than)
Step-by-step explanation:
since abs value changes it to positive it would be
5 and 9
5 < 9
Answer:
The answer is C because they have the same coefficient and variable on both sides (or something like that but its definitely c )
The answer is 8x.
You are combining like terms as 5 and 3 both have x so you are simply adding 5+3= 8
