Answer:
the roots of 3x2-5-1 is X=1 I think soo
Okay I know how to do this, first set it up as
161 X
-----=------
575 100
Then cross multiply
|____|____|____|____|____|____|____|____|
0 1/16 2/16 3/16 4/16 5/16 6/16 7/16 8/16
| _________________| _________________|
0 1/4 2/4
Answer:
9m^3
Step-by-step explanation:
Seperate the shape to two shapes. Two rectangles.
Volume of the bottom rectangle：3X2X1=6
Volume of the top rectangle：1X1.5X2=3
6+3=9
|2x-3|=2x-1
need to consider two cases
(1) 2x-3<0 --> x<3/2
-(2x-3)=2x-1
x=1, and this is <3/2 so that's a valid solution
(2) 2x-3>=0 --> x>=3/2
2x-3=2x-1
-3 = -1 so there no solution for x>=3/2
The single solution is x=-1
