Please help number 9 A living room is 19 feet wide. The carpeted portion of the room is 5x feet long and the adjacent 9) tiled portion of the room is 7y feet long. Use the distributive property to find an expression for the
total area of the living room.
A) 95x + 133y square feet B) 24x + 26y square feet C) 228(x + y) square feet D) 95x + 7y square feet

Option A. 95x + 133y square feet.

Step-by-step explanation:

Area of a rectangular room = Length × Width

Length of the room = Length of carpeted portion + Length of the tiled portion

= (5x + 7y) feet

Width of the living room = 19 feet

Area of the living room = (5x + 7y) × 19

                                      = 95x + 133y Square feet [By distributive property]

Therefore, expression for the total area of the living room is option (A).

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".
