Answer:
x³ − x² + 9x − 9 = 0
Step-by-step explanation:
Imaginary roots come in conjugate pairs. So if 3i is a root, then -3i is also a root.
(x − 1) (x − 3i) (x − (-3i)) = 0
(x − 1) (x − 3i) (x + 3i) = 0
(x − 1) (x² − 9i²) = 0
(x − 1) (x² + 9) = 0
x (x² + 9) − (x² + 9) = 0
x³ + 9x − x² − 9 = 0
x³ − x² + 9x − 9 = 0
Answer:
108 dollars
Step-by-step explanation:
Cause first you have to find the unit rate of one lollipop which is 2 and then multiply that by a dozen which is 12 and you add that to the product of 3 times 24 which is 84 and 84 plus 24 gives you 108 and then you put the unit on it dollars so 108 dollars

Answer:

Step-by-step explanation:
I think your missing numbers are
RBC = 2.5 × 10¹³ and
WBC = 7 × 10¹⁰
This is a ratio question.
You are asked to find the ratio of RBCs to WBCs.
Let r = the ratio.
Then the equation for the ratio is

Insert the values and do the division.
