Answer:
2c^2 - 2c - 3
Step-by-step explanation:
Next time, please share the answer choices. Thank you.
Group together the 'c' terms in 2 + 7c – 4c2 – 3c + 4:
2 + 4c and -4c^2 + 4 Then we have:
-4c^2 + 4c + 6
We should reduce this by factoring -2 out of all three terms:
2c^2 - 2c - 3 This is the desired quadratic in standard form.
The correct answer would be C
600:450 divided by 10 = 60:45
60:45 divided by 15 = 4:3
so 4:3 x 15 = 60:45 x 10 = 600:450
Answer:
Her actual distance for the trip will be 112.5 miles.
Step-by-step explanation:
You need to analize the information provided in the exercise.
You know that the scale of the map Kelsey is reading is:

And according to the exercise, Kelsey's trip measures 4.5 inches on that map.
Therefore, in order to calculate what will be her actual distance for the trip (Let be
this distance), you can set up the following proportion:

Finally, you must solve for
. Then, you get:

Therefore, her actual distance for the trip will be 112.5 miles
They're just variables, they can stand for anything. They're not that important. But h unsually stands for hours
