True or false? if a circle is circumscribed about a parallelogram, the parallelogram must be a rectangle.

True, If a circle is circumscribed about a parallelogram, the parallelogram must be a rectangle.

Step-by-step explanation:

It is true statement.

Since we know that if a circle is circumscribed about a parallelogram, the parallelogram must be a rectangle.

As circumscribed parallelogram has the sum of opposite sides of the parallelogram is supplementary.

So, each angle becomes right angle and we know the property of parallelogram that opposite sides are equal.

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
