A quadratic function is given by () = 2 + + . The points (0, 5) and (−4, 5) lie on
the graph of = (). The -coordinate of the minimum of the graph is 3. Find the value of and
of .

answer is more than one

step-by-step explanation:

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".

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
