Answer:
Okay so for this you will use the FOIL (first, outer, inner, last) method.
Step-by-step explanation:
So, first you take the x from (x-3) and multiply it by the x in (x-4).
So, now you have x^2
Then you do the outer which would be x multiplied by 4.
Now you have -4x.
Then you multiply the inner which is -3 times x.
Which is -3x.
Now its the last which is -3 times -4 which equals 12.
Now you put them in order:
x^2 - 4x - 3x + 12
Lastly, you combine like terms:
x^2 -1 + 12
Find the scale for how many miles per inch are on the map:
270 miles / 4.5 inches = 60 miles per inch.
On the map every 1 inch equals 60 miles.
12 inches x 60 miles per inch = 720 miles total.
City B and City C are 720 miles apart
Answer:
x coordinate B
Step-by-step explanation:
cos is always x coordinates, and it is a 3pi/4 rotation
Simplified to its simplest form would be 15/4. The GCD of them all would 400, so you divided them by 400.
