Answer:
B) 
Step-by-step explanation:
First simplify the radical on the right.
is equal to
, because 25 * 3 is 75, so we can separate the square roots into the product of these two square roots.
Then we know
is just equal to 25, which means the simplified version of
is
.
Then we can use this new representation to finish solving.
, so the answer would be B
For this case we must find the solution of the following quadratic equation:

Where:

Then, the solution is given by:

Substituting the values:

By definition we have:

Thus, we have two complex roots.
Answer:
The equation has no real roots.
Answer:
B
Step-by-step explanation:
Multiply each term by -10
44% + 48% = 92%
48% go, 44% dont go...so thats 92% that either go or dont go....leaving u with 8% unsure
0.08(650) = 52 are not sure they will attend
