Answer:4x+3
Explanation:
Given the following in the question if:
Volume of the box= 4x3+19x2+12z
Height of the box= x
width of the box =?
we have to find the width of the box, so as we know that
box is in the shape of cuboid, so
Volume of the cuboid = length * width * height
4x3+9x2+12x = x+4* width * x
width = 4x3+9x2+2x/x2+4x
we have to use long division method for this algebraic expression to divide and find width of the box.
we get width= 4x+3
Hence, the width of the box which in the shape of cuboid is 4x+3
