The length of a rectangle is two less than three times a number x and the width is five more than that same number. WHAT IS THE EXPRESSION that represents the LENGTH of the rectangle

3x - 2

Step-by-step explanation:

From the above question, we are told that:

The length of a rectangle is two less than three times a number x

Expressing this Mathematically:

3× x - 2

= 3x - 2

Also:

the width is five more than that same number.

Width = x + 5

Therefore, THE EXPRESSION that represents the LENGTH of the rectangle is 3x - 2

2

step-by-step explanation:

1+1=2

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".
