x <-1
Step-by-step explanation:
x + 12 < 8 − 3x
Add 3x to each side
x+3x + 12 < 8 − 3x+3x
4x+12 < 8
Subtract 12 from each side
4x+12-12 <8-12
4x<-4
Divide each side by 4
4x/4 <-4/4
the bottom of the spinner is not flat.
step-by-step explanation:
answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
