A pizza parlor uses square prisms for their pizza boxes. Due to the crust rising, the height of their boxes is always 2 inches. Additionally, the volume of the pizza box must be 450 cubic inches to fit their standard-sized pizza. A worker determined that the equation 2x2 = 450 could be used to find the side length, x, of the box needed to reach that volume. Determine which statement is true about the solutions to the equation.

A.
The solutions are -30 and 30 but only 30 is a reasonable side length.
B.
The solutions are -30 and 30 and both are reasonable side lengths.
C.
The solutions are -15 and 15, but only 15 is a reasonable side length.
D.
The solutions are -15 and 15 and both are reasonable side lengths.

B.

The solutions are -30 and 30 and both are reasonable side lengths.

Step-by-step explanation:

sorry

if I 'm wrong

2 is the final ! : )

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
