1.5 × 10^(-4). .....this the scientific notation !
Answer:
10
Step-by-step explanation:
GIVEN: Josiah is playing a computer game that lets him customize a story There are
different eras and
location to choose from.
TO FIND: How many different stories can Josiah construct.
SOLUTION:
Total different eras 
Total different locations 
He can choose one era and one location.
Total different stories that Josiah can construct 

Hence Josiah can construct 10 different stories.
So it's like 'which one of the number given is a factor of, say, 10' and the choices are 4,5,7,9. the answer is 5 so just factor out the equation
the factored out form is
factor out the 3x^2 and get
(3x^2)(3x^2-2x+1)
and 3x^2-2x+1 is the fourth choice
Answer:
18x
Step-by-step explanation:
If f(x) is 5x which can also be expressed 5(x)
Then r(x) is a number then x
f is the fifth digit in the alphabet
So fx is 5x
r is the 18 th letter so
18x
Answer: $56
