9 x 10^2 is ? times as much as 3 x 10^-2. A. 6 x 10^0
B. 3 x 10^-4
C. 6 x 10^4
D. 3 x 10^4

3 × 10^4

Step-by-step explanation:

9x10^2 is how many times as much as 3x10^-2?

9 × 10^2 = 9 × 100 = 900

3 × 10^-2 = 3 × 0.01 = 0.03

We then divide, this will be:

= 900/0.03

= 30000

This can be represented as:

30000 = 3 × 10^4

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
