Answer: False, there are actually 900 different three-digit numbers
========================================================
Explanation:
The three digit numbers span from 100 to 999, including both endpoints.
This means we have 999-100+1 = 900 different three-digit numbers.
You subtract the endpoints (large-small) and add 1 to include the lower endpoint.
Here's a smaller example of why this works: say you had the set {1,2,3,4} and we wanted to count the number of items in this set. Clearly there are 4 items. Note how subtracting the endpoints 4-1 gets us 3 instead, so we add on 1 to include that left endpoint.

10^8
it means multiply 10 8 times so
10*10*10*10*10*10*10*10
=100000000

Answer:
The standard form is: y = -3x² +18x -24.
Step-by-step explanation:
Given is y = -3(x-2)(x-4)
Using FOIL method to expand the parentheses:-
y = -3(x-2)(x-4)
y = -3(x² -2x -4x +8)
Combining like terms:-
y = -3(x² -6x +8)
Distributing -3 to the terms inside parentheses:-
y = -3x² +18x -24.
Hence, standard form is: y = -3x² +18x -24.
