which number is a factor of 40?
2 x 5
2 x 20
2 x 2 x 2 x 5
2 x 2 x 4 x 5

2 x 2 x 2 x 5

Step-by-step explanation:

40 = 4 * 10

Factor

      = 2*2   * 5*2

Putting them in order from smallest to largest

      = 2 *2 * 2 *5

2 x 5  = 10

2 x 20 =40  Factor of 40

2 x 2 x 2 x 5 = 40   Prime factorization of 40

2 x 2 x 4 x 5 = 80

I think you are looking for the prime factorization of 40, which means breaking the numbers down into primes.

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
