2x + 2 -3x -15 > 0
-x-13 > 0
-x > 13
Answer: x < -13
Getting the central area of a polygon is not possible. Probably the question refers to the central angle. In a a regular polygon, getting the central angle is that you need to use the formula.
Central Angle of a polygon = 360 degrees / number of sides of a polygon.
Why 360 degrees? Because, a circle has a total of 360 degrees. And a circle is a polygon with no sides.
Answer:
Look at 0 next to the dot. It's less than 5. Then round 3.0xxxx to 3.
Step-by-step explanation:
Answer:x/6 + 1 = 4
x= 18
7x+ 4=11
x=1
Step-by-step explanation:
For both questions do inverse operation.

Answer:
Since we have two semi-circles we can say that we have a full circle. using the circle area formula we can say that
3.14*2^2 = 12.56 cm
Using the rectangle area formula we can say that
19*4 = 76 cm
Adding them both together is
12.56 + 76 = 88.56 cm
So the bookmark has an area of 88.56cm^2
