Answer:
B.) why Factor p+ 12r - 6, I did not do that below.
Step-by-step explanation:
r^2+12r-6=0
solve:
r^2 + 12 r + 36 - 36 - 6 = 0
factor the trinomial by completing the square.
( r + 6)^2 -42 = 0
(r + 6)^2 = 42
r + 6 = root(42 ) or r + 6 = - root(42)
r = -6 + root(42) or r = -6 -root(42)
I can confirm that it is A as I took the test and got 100%.
Answer:

Step-by-step explanation:
The problem is asking for the fraction to be divided by a whole number. This is equal to multiplying a fraction by the reciprocal of the whole number.


Then you can multiply like a regular multiplication problem

The final answer would be 
Answer:
26 + 22i
Step-by-step explanation:
Given
(2 + 4i)(7 - 3i) ← expand product using FOIL
= 14 - 6i + 28i - 12i² ← i² = - 1
= 14 + 22i + 12
= 26 + 22i ← in standard form
It’s b, the other expressions equal each other :)
