Answer:
The missing number is 4
Step-by-step explanation:
Given
21 x 39 x _____ x 19 divided by 12 = 5187
Required
Fill in the gap
Let the missing number be represented with y; So, the expression becomes

Multiply both sides by 12


Rearrange the expression on the left hand side


Divide both sides by 15561



Hence, the missing number is 4
The student can compare all the measurements and whichever one is the most different out of all the measurements will be the least precise
Answer:
A path that goes through every EDGE once and starts and ends at different vertices.
Explanation:
A "Euler path" is a trail that is being used in a graph consisting of finite number of edges. It is also known as "Eulerian path." This should be contrasted from the "Euler circuit," for both of their meanings are a bit confusing.
A Euler path only uses every edge of the graph once and it starts and ends at<em> different vertice</em>s. A Euler circuit, on the other hand, uses every edge of the graph exactly once but <em>starts and ends at the same vertex</em>.
So, this explains the answer.
Answer:
square units
Step-by-step explanation:
We are given that two vectors
u=<3,2,1>
v=<1,2,3>
We have to find the area of parallelogram determined by the given vectors


We know that area of parallelogram determined by two vectors a and b

Using this formula



Area of parallelogram=
square units
