Sqrt(27)+sqrt(48)+sqrt(12)
Sqrt(27)=sqrt(3*3*3)=3*sqrt(3)
Sqrt(48)=sqrt(4*4*3)=4*sqrt(3)
Sqrt(12)=sqrt(2*2*3)=2*sqrt(3)
Add the three to get 9*sqrt(3)
Final answer:
9*sqrt(3)

Answer:
2,000 miles
Step-by-step explanation:
We are given:
![1 inch=500 miles](https://tex.z-dn.net/?f=1%20inch%3D500%20miles)
This can be rewritten as:
![\frac{500 miles}{1inch}](https://tex.z-dn.net/?f=%5Cfrac%7B500%20miles%7D%7B1inch%7D)
This is representative of a unit rate, as we have a
in the denominator. To calculate the number of miles in
inches, simply multiply the unit rate by
:
![\frac{500 miles}{1inch}*4=](https://tex.z-dn.net/?f=%5Cfrac%7B500%20miles%7D%7B1inch%7D%2A4%3D)
![\frac{2000 miles}{4 inches}](https://tex.z-dn.net/?f=%5Cfrac%7B2000%20miles%7D%7B4%20inches%7D)
This can rewritten as:
![4inches=2000miles](https://tex.z-dn.net/?f=4inches%3D2000miles)
Therefore, there are 2,000 miles in 4 inches.

We can check our solution by simplifying the fraction
by dividing both
and
by
to see if we achieve the unit rate:
![\frac{500 miles}{1 inch}](https://tex.z-dn.net/?f=%5Cfrac%7B500%20miles%7D%7B1%20inch%7D)
Since this is in fact the unit rate, our solution is correct!
Answer:
-2
Step-by-step explanation:
The slope of a line tells us how y responds to a change in x. If the slope is 2, it means that for every time x increases by 1, will will go up by 2.
We can calculate slope from a line, or with two given points. I used points (0,4) and (3,-2). Slope is the "Rise/Run."
The Rise: (-2 - 4) = -6
The Run: (3 - 0) = 3
Slope = Rise/Run = (-6/3) = -2

Answer:
First one would be D (( A'(-3,-6), B'(-5,-4), C'(0,-4) ))
The second would be D (( A'(-15,8), B'(-4,5), C'(-9,6) )) as well
