$230 is a one time cost, regardless of how many days they stay on the trip.
X has to be inside the radical.
It would be

Simplify the radical by breaking the radicand up into a product of known factors.
Answer:
f(-1) = 2
f(0) = 3
Step-by-step explanation:
f(a) = 3a - a²
f(4)= 3*4-4²= -4 ⇒ correct
f(3)= 3*3-3²= 0 ⇒ correct
f(-1) = 3*(-1)-(-1)²=-3+1= -2 ⇒ incorrect
f(0) = 3*0-0²= 0 ⇒ incorrect
f(-5) = 3*(-5)-(-5)²= -15-25= -40 ⇒ correct
We are asked to write the following fraction of complex numbers in standard form:

.
Whenever we are dividing by a complex number by another complex number a+bi, to write the result in standard form, we multiply the expressions in the numerator and denominator by the conjugate of a+bi, that is a-bi:

in the numerator we distribute (3-i) to 1 and -5i, in the denominator we use the difference of squares formula

, and

:
