A parallelogram with four congruent sides is called a rhombus.
3x(x^2+4)
3x(x^2)+3x(4)
=3x^3+12x
Answer:
5
Step-by-step explanation:
We know that 13 is the hypotenuse. With this we can use the Pythagorean Theorem to solve this problem.
Let the third side be x.
13^2=12^2+x^2
169=144+x^2
169-144=x^2
25=x^2
x=5
Solved.
The plane is 2 dimensional because it has height and width, which is a total of 2 dimensions.
The third choice is your answer since it is the only choice that has the proper dimension along with the proper explanation.
Have an awesome day! :)
