A:
Answer:8.5 bags are needed.Step-by-step explanation:Given : Number of bags needed [tex]B=x(2x+7)+3(2x+7)+(x+4)[/tex] [tex](2x + 7) = 4[/tex]To Find : how many bags he needs?Solution :[tex](2x + 7) = 4[/tex][tex]2x=-3[/tex][tex]x=-\frac{3}{2}[/tex]Now we are given that Number of bags needed [tex]B=x(2x+7)+3(2x+7)+(x+4)[/tex]Substitute the value of x [tex]B=(\frac{-3}{2})(2(\frac{-3}{2})+7)+3(2(\frac{-3}{2})+7)+((\frac{-3}{2})+4)[/tex][tex]B=8.5[/tex]Hence 8.5 bags are needed.
