i believe that it’s a but i don’t want to get it wrong can someone help me (no wrong answers pleaseee)
VARVARA [1.3K]

Answer:

B

Step-by-step explanation:

For the divisor on the left of the division symbol, the -3 symbolizes that the -3 is a root. This means that when we plug -3 into our divisor, the answer is 0. Therefore, as x+3=0 when x=-3, the divisor is x+3.

Next, for the dividend, we can start on the left with no x multiplied to it and then add one degree of x for each value to the left. This results in

6 + -4 * x¹ + 4 * x² + 2 *x³

= 2x³ +4x² -4x+6

Let log p/n=6 and log m/n=8 what is the relationship between p and m?
Mrac [35]
By the laws of logs
log p/n =  log p - log n  = 6
log m/n = log m - log n   = 8        subtract
 
 log m - log p =  2
 
log m/p = 2

So m / p = 100
