The area of a polygon equals
area = circumradius² * number of sides * sin (360 / # of sides) / 2
area = 77² * 20 * sin (360 / 20) / 2
area = 77² * 20 * sin (18) / 2
area = 118,580 * 0.30902 / 2
area =

/ 2
area =
18,321.8 square millimeters
<span>4x^2 - 25
= (2x)^2 - 5^2 .................using a^2 - b^2 = (a+b)(a-b)
= (2x + 5)(2x - 5)</span>

34.
- h(x) = 8 ⇒
- x = 4 as per diagram
35.
36.
- f(x) = 2 ⇒
- x = -0.8 as per graph (approx.)
37.
38.
- h(-1) = -8 as per diagram
39.
- g(x) = 4 ⇒
- x = 9 or x = 8 as per table
Answer:
C=4
Step-by-step explanation:
So you multiply 3 tickets by 25 and you get $75. You then subtract $130 from $75 and you get $55 you then multiply 12 by 4 to get $48. And that's how 4 is the correct answer.
