The spokes of a bicycle wheel form 10 congruent central angles. The diameter of the circle formed by the outer edge of the wheel
N76 [4]

find the circumference and divide it by 10

c = d\pi \\ c = 18\pi \\ c = 56.548668... \\  \\ arc =  \frac{c}{10}  \\ arc = 5.654867... \\ arc = 5.7

4/4 plus 4/4 please help
krek1111 [17]
Simplifying is basically 1 + 1, so the answer is 2, or 8/4 whichever you prefer. 
It can also be 4/2, or 2/1...

Hey, can I please get some help with this? It shouldn’t be too hard, thanks!

Answer:

  • (x -3)(x+3)(2x +1)
  • (x -1)(x +1)(x +3)
  • (2x -1)(2x +1)(x -4)

Step-by-step explanation:

A) 2x³ +x² -18x -9 = x²(2x +1) -9(2x +1) = (x² -9)(2x +1) = (x -3)(x+3)(2x +1)

__

B) x³ +3x² -x -3 = x²(x +3) -1(x +3) = (x² -1)(x +3) = (x -1)(x +1)(x +3)

__

C) 4x³ -16x² -x +4 = 4x²(x -4) -1(x -4) = (4x² -1)(x -4) = (2x -1)(2x +1)(x -4)

_____

In each case, the third-level factoring mentioned in step 4 is the factoring of the difference of squares: a² -b² = (a -b)(a +b).

_____

The step-by-step is exactly what you need to do. It is simply a matter of following those instructions. You do have to be able to recognize the common factors of a pair of terms. That will be the GCF of the numbers and the least powers of the common variables.
