Try to find the common factor which is 2.
So:
Multiply by 2 both variables in parenthesis and you get:
2*(l+w)
<em>The dimensions of the cardboard to make a box without a lid is 11 inches by 11 inches.</em>
<h2>
Explanation:</h2>
In this problem, we have that Isabelle is using a square piece of cardboard to make a box without a lid. She cuts 2-inch squares from each corner and folds up the edges. The figure below shows this statement. The finished box has a volume (V) of 98 cubic inches, in other words:

When folding up, we get the box without lip shown in the second figure. So the volume would be:

Since te cardboard is square, then the side (s) is given by:

Therefore:
<em>The dimensions of the cardboard to make a box without a lid is 11 inches by 11 inches.</em>

Answer:
Step-by-step explanation:
There are many such polynomials, but the one with leading coefficient of 1 is
y = (x+1)(x-1)(x-6) = x^3 - 6x^2 - x + 6
Not sure what you want to do with the 5, If that is the y-intercept, then since
(1)(-1)(-6) = 6, we will need
y = 5/6 (x^3 - 6x^2 - x + 6)
