Answer:
5.25ft
Step-by-step explanation:
i got the question right so thats it
For this problem, I have to know the amount of distance to get to Room 117. If I do, I can give an exact answer to this problem. Through dimensional analysis, you have divide distance with speed to determine the time:
Time = Distance/Speed
Time = d/4
As long as you know the distance, when you substitute it to d in the equation, you can already answer the time.
Answer:
-1
Step-by-step explanation:
To factor x²-2x-4, you are looking to answer three questions.
1) What pair of numbers multiplies to 4?
2) What pair of numbers multiplies to 1?
3) Do these pairs when multiplied together, add/subtract to the middle term?
To answer (1), our pairs are 2 and 2, 4 and 1. Since there's a negative with 4 at the end (from question one), the signs will be opposite.
To answer (2), only pair multiplies to 1 - 1 and 1. Let's try both pairs from 1.
(x-4)(x+1) The middle term here is -3x. Nope.
(x-1)(x+4). The middle term here is 3x. Nope.
(x-2)(x+2) The middle term is 0x (or no middle term). Nope.
So x²-2x-4 does not factor.
