-8 > -5x + 2 > -38
Subtract 2 from all 3 "sides"
-10 > -5x > -40
Divide by -5. Flip the > signs to <.
2 < x < 8

-8 > -5x + 2 > -38...subtract 2
-8 - 2 > -5x + 2 - 2 > -38 - 2
-10 > -5x > -40 ... now divide by -5, and change inequality sign
-10/-5 < (-5/-5)x < -40/-5
2 < x < 8

The formula for finding the volume of a rectangular prism can be stated as V= l x w x h, wHerr l=length of the prism, w=width of

blagie [28]

Answer:

23265

9478.125

3) 102369.09375

Formula nonsense: V=l*w*h

1) meaning V= 33*47*15 so V= 23265

2) meaning V= 22.5*33.7*12.5 so V= 9478.125

3) meaning V= 122.25*50.75*16.5 so V= 102369.09375
