Draw a number line -5through 5 and mark 0≤x≤2

Step-by-step explanation:

The answer to the question above is drawn in the attached picture.

Note that the symbol, less than or equal to, is a shaded ring. Also, the inequality is interpreted as zero is less than or equals x and x is less than or equals 2. Hence, the joint inequality is presented as shown in the attached picture.

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".

i dont understand the question? ?
