Answer:
I believe the answer you chose is correct. D
A rectangular prism is a cuboid so volume of cuboid is base area x height which is 5x5x12=300
volume of pyramid is 1/3 x base area x height = 5x5x6x1/3=50 thus volume outside pyramid and inside cuboid is 300-50=250
3-4x=-6x^2
+6x^2=+6x^2
_____________
6x^2+3-4x=0
6x^2-4x+3=0
(-4)^2-4(6)(3)
16-72
Final Answer: -56
The mean, since it's the average of whatever your data is.
3(x+4)+2= 2+5(x-4)
3x+12+2= 2+ 5x-20
3x+14= 5x-18
3x+14-14= 5x-18-14
3x= 5x-32
3x-5x = 5x-32-5x
-2x= -32
-2x/ -2= -32/-2
x= 16
So answer A combine
