The tops and bottoms of a trapezoid are parallel, and a polygon's volume and angles are always 360.As long as you know the shape and about three of the lengths, you can find the base.
Answer:
A complex number is of type
a+bi
where a is the real parts and b is the imaginary part.
Step-by-step explanation:
A complex number is of type
a+bi
where a is the real parts and b is the imaginary part.
i is called imaginary number because no real number satisfies this equation
An example of complex number can be: 7+8i or 23+9i etc

Equation that can be used to find t
1 large table can take 15 people and there is only one large table.
So, we have:

1 small table can take 5 people and there are t small tables.
So, we have:

The room can accommodate 140 people.
So, we have:

This gives:

<em>The above expression can be used to determine the number of small tables</em>
