Answer:
Cost of packing 3 boxes = 3*(2LW + 2WH + 2LH) * 0.02 dollars
Step-by-step explanation:
Assume length of box = L in
height of box = H in
width of box = W in
surface area = (2LW + 2WH + 2LH) sq. in.
surface area of 3 boxes = 3*(2LW + 2WH + 2LH) sq.in.
Cost of packng one sq. in.= 0.02 dollars
Cost of packing 3 boxes = 3*(2LW + 2WH + 2LH) * 0.02 dollars
Answer:
4r^3+8r^2-5r-10
= 4r^2(r+2)-5(r+2) [Factorise out like terms; distributive law of multiplication to check]
=(4r^2-5)(r+2) [Combine expressions]
