Given triangle ABC with vertices A (2, rectangle1), B (5,6) and C (-1,4) as shown find the number of square units in the area of triangleABC in simplest form

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

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".

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
