Answer:

Step-by-step explanation:
1) In this question we've been given "a", the leading coefficient. and two roots:

2) There's a theorem, called the Irrational Theorem Root that states:
If one root is in this form
then its conjugate
. is also a root of this polynomial.
Therefore

3) So, applying this Theorem we can rewrite the equation, by factoring. Remembering that x is the root. Since the question wants it in this expanded form then:

Answer:
15x3y.
Step-by-step explanation:
.
Answer:
It is an obtuse angle!
Step-by-step explanation:
The doctor would have 72 patients each week. Meaning 3744 each year.
Answer:
B.
Step-by-step explanation:
If you simple this expression we can see that 7/35 will simplify to 1/5 first. As for the exponents, you can write them out to make it easier to cancel, shown in the photo.
