Hello there! You can do something like this:
Kelly has 3/4 cup of a bottle of water. She likes to drink 5 times the amount of that every day. How many cups of water does Kelly like to drink every day?
Hope this helped you!
Good luck!
Density = m/v
3.86kg=3860g
d= 3860/200
= 19.3g/cm^3
therefore it is gold.
Plug the points into the distance formula.
d= (sqrt) (x2-x1)^2+(y2-y1)^2
Plug the first set of points in. (-2,1) (6,1)
d= (sqrt) (6-(-2))^2+(1-1)^2
d= (sqrt) (6+2)^2+(0)^2
d= (sqrt) 8^2+0
d= (sqrt) 64
d= 8
Now, find the distance for the other two points. (6,1) (6,-3)
Q to R.
d= (sqrt) (x2-x1)^2+(y2-y1)^2
d= (sqrt) (6-6)^2 +(-3-1)^2
d= (sqrt) 0^2+-4^2
d= (sqrt) 16
d= 4
Now, finally, find the distance between R and S. (6,-3) and (9,-3)
d= (sqrt) (x2-x1)^2 + (y2-y1)^2
d= (sqrt) (9-6)^2+ (-3-(-3)^2
d= (sqrt) 3^2+ 0^2
d= (sqrt) 9
d= 3
Now, add all those distances together.
8+4+3= 15
"B" is the correct answer. 15 units.
I hope this helps!

Answer:
2x^2*(2x^3+8x^2+2x) or
4x^5+16x^4+4x^3
Step-by-step explanation:
A=[2x^3-x+(8x^2+3x)]*4x^2/2=2x^2*(2x^3+8x^2+2x)
or A=4x^5+16x^4+4x^3
