Answer:
69.08 is the answer
Step-by-step explanation:
F(8)=120
f(x)=15x
f(8)=15(8)
f(8)=120
x=0 or x=4
just factorize basically
cancels the x’s so it’d be 3x-12=0 and from that x=4
A U B = {1,2,3,4,5,6,8}
Let's define the sets.
Let ¢ = universal set ( Contains all the elements in the set)
¢ = {1, 2, 3, 4, 5, 6, 7, 8, 9 , 10}
A= {2, 4, 6, 8}
B= {1,2,3,4,5,6}
Therefore: A U B (A union B):
A U B = {1, 2, 3, 4, 5, 6, 8}
