Simply plug in x = 0
f(x) = x^2 - 5
f(0) = 0^2 - 5
f(0) = -5
Answer: -5
Answer:
(x-2)(x^2+2x+4)
Step-by-step explanation:
x^3-8
x^3-2^3, Now using the base equation for the difference of cubes
(x-y) (x+xy+y^2), y is equal to -2 in this instance.
(x-2)(x+2x+4)
Lucy started with 12 books and gave 3 which is 12-3=9
Lucy has 9 books m
It took him 1 hour and 30 mins .
He needs to go 15 miles. It takes him 1 hour to get 10 miles. After 1 hour has passed he still needs 5 more miles to go. 5 miles is half of 10 so half of 1 hour is 30 mins. 1 hour + 30 mins is 1 hour and 30 mins. (It took him 1 hour 30 mins)
