Answer:
6(x + 9) (x + 9)
or

Step-by-step explanation:

Greatest common factor of 6, 108, and 486:
6 x 1 = 6
6 x 18 = 108
6 x 81 = 486
GCF: 6
so:


factors to:
(x + 9) (x + 9)
because:
9 x 9 = 81
9 + 9 = 18
So:
It factors completely too:
6(x + 9) (x + 9)
or

Answer:
49,400,000
Step-by-step explanation:
(2.6*10^5)(1.9*10^2)
Apply exponent rule
=2.6*1.9*10^5+2
Add the numbers: 5+2=7
=2.6*1.9*10^7
Multiply the numbers: 2.6*1.9= 4.94
10^7*4.94
10^7=10,000,000
=10,000,000*4.94
Multiply the numbers: 4.94*10000000=49,400,000
=49,400,000
Thanks for letting me help!!
From the question, we know the population standard deviation, σ = 1.63, the sample standard deviation, s = 3.07, the sample mean,

and the sample size, n = 38.
