Plz show all work sabrina is making an open box from a piece of cardboard that has a width of 12 inches and a length of 18 inches. she’ll form the box by making cuts at the corners and folding up the sides so that the flaps are square. if she wants the box to have a volume of 224 in3, how long should she make the cuts? part i: given what you know about the box sabrina is making, write a polynomial to represent each dimension (width, length, and height) of the finished box. (3 points) width = length = height = part ii: the formula for volume is v = l • w • h. write an equation to represent the volume of the box. simplify on the right side by multiplying the polynomials and writing the answer in descending order. show your work. hint: first multiply the binomials representing length and width. next, multiply the resulting trinomial by the expression representing height. (3 points) v = part iii: the length of each cut at the corners is represented by x. to make a box, x must fall in a certain range of values. for example, x cannot be 15 because that would make the flap longer than the width of the box. identify one reasonable value of x. why did you choose that value? (1 point)

Drag each expression to the correct location on the solution. not all expressions will be used. consider the polynomial 8x + 2x2 - 20x - 5. factor by grouping to write the polynomial in factored form.
