Which of the following is a area of the special trepezoid if ab=19,cd=19 and the height is 14
tankabanditka [31]

As, Opposite side of Special trapezoid is equal.So, it will be a Parallelogram.

ab=c d= 19 units

Height of Trapezoid = 14 units

Area of Trapezoid =  \frac{1}{2} \times {\text{Sum of parallel sides}} \times {\text{Perpendicular Distance between them}}

  =\frac{1}{2}\times (19+19) \times 14\\\\ =\frac{1}{2} \times 38 \times 14\\\\ = 19 \times 14\\\\= 266

So, Area of Trapezoid = 266 square units

You, can use the formula for finding the area of parallelogram,which is = Base on which perpendicular is drawn × Length of Altitude

= 19 × 14

= 266 square units

Use set builder notation to write each of the following sets 45,55,65,75
butalik [34]

Answer: \{ x: x =5(2n+1) ,4\leq n\leq 7 ,x,n\in N \}

Explanation:

As we know that set is the collection of elements and set builder is the method of defining the set with the help of specific property in which we can use arithmetic operations as well

Generally,

It is the general form of any set in which we can construct the complete set  with the help of equation in the given in set builder form.

Since we have the elements : 45,55,65,75

So, the set builder form will be { x: x =5(2n+1) ,4≤n≤7,x,n∈ N }

We will read it as it is the value of x which will be find with the help of given equation i.e. x=5(2n+1) where n goes from 4 to 7 only and x and n are natural numbers only.
