Step-by-step explanation:
3(6+b)+2b+1
18+3b+2b+1
5b+19
Volume = (l*h*w)\3
v= (20*15*15)\3
v=4500\3
v=1500
Answer:
; 
Step-by-step explanation:
we know that
step 1
Find the inequality of the solid line x+3y=6
The solution is the shaded area below the solid line
therefore
The equation of the inequality is

step 2
Find the inequality of the solid line y=3x-1
The solution is the shaded area above the solid line
therefore
The equation of the inequality is

therefore
The system of linear inequalities is
