28:13 is the answer i’m pretty for sure
Answer:
72 
Step-by-step explanation:
Volume for a triangular prism =
a · c · h
A = Height. C = Width. H = Length.
A = 3 yd. C = 8 yd. H = 6 yd.
V = 114 yd.
V = 114 yd ÷ 2 yd = 72
.
646/3=x
To check it: x*3 should =646
I dont know how to solve it but since the answer shows as 6 and -7, if you plug it in as x values, one tiem as 6 and second time as -7 it doesnt equal 42
