Which student’s answer most accurately describes the solution to the inequality x less-than negative 3? Andie’s Solution -contains only negative rational numbers -has a lower limit of –3 and no maximum value Bobby’s Solution -contains positive and negative rational numbers -has an upper limit of –3 and no minimum value Carrie’s Solution -contains positive and negative rational numbers -has a lower limit of –3 and no maximum value Deshawn’s Solution -contains only negative rational numbers -has an upper limit of –3 and no minimum value

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".

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
