The answer is letter c. x2-8x+24-[72/(x+3)]. If you do not know how to solve this using the long division method, you can always evaluate the options through the process of elimination first. Since the degree of the other factor is already 1 (x to the power of 1), you know that option d. is not the correct answer because you know that the other factor must be raised to the power of 2. That leaves us with a, b and c. Working backwards and multiplying the given factor (x+3) with the factor in b, gives us x3-5x2+72. So from there, you know that you have to eliminate 72, which can be removed when it is subtracted by itself. Letter c does just that. Try multiplying (x+3) and option c for yourself :).
I need points for a test please don’t report
3.0 x 10^8 km/s is how far light travels.
3.0 x 10^8 km/s x 60s is how far light travels in a minute
3.0 x 10^8 x 60 x 5 is how far light travels in 5 minutes, and you should get D as your answer.
Answer:
<u>The correct answer is 15.72 or 6 ∛18</u>
Step-by-step explanation:
Let's calculate the cube root of 216 * 18
∛(216 * 18)
216 = 8 * 27
8 = 2³; 27 = 3³
18 = 9 * 2 or 3² * 2
∛(8 * 27 * 18)
Simplifying:
∛(2³ * 3³ * 3² * 2)
∛(2³ * 3³ * 3² * 2)
2 * 3 ∛(3² * 2
<u>6 * 2.62 = 15.72 or 6 ∛18</u>
