13. Because it can't be divided by a whole number except 1 and itself. 14 can be Divided by 2. 21 and 33 can be divided by 3 making them composite or divisible by more than just 1 and itself :)
Top one is 56
-9 + <u>112 </u>= 7(x2 - 8x + <u>16 </u>)
sin(8x) cos(3x) - cos(8x) sin(3x)
sin(8x - 3x) = sin(5x)
Answer:
The answer to your question is 10 in
Step-by-step explanation:
Data
Circumference = 20π in
Diameter = ?
Formula
Circumference = 2πr
Process
1.- Equal the formula to the value
2πr = 20π
2.- Solve for r
r = 20π/2π
3.- Simplification
r = 10/2
4.- Find the diameter
diameter = 2r
diameter = 2(10/2)
diameter = 10 in
