Consider u = {x|x is a positive integer greater than 1}. which is an empty set?
a. {x|x ∈ u andone-half is prime}
b.{x|x ∈ u and 2x is prime}
c. {x|x ∈ u andone-half can be written as a fraction}
d. {x|x ∈ u and 2x can be written as a fraction}

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

step-by-step explanation:

b

step-by-step explanation:

multiply terms on numerator/ denominator by (x - 1)

= ← distribute numerator/ denominator

= ← simplify

=

= → b
