The interest that cindy earns on her investment is given by the equation l = 42t where t is the time in years that her money is invested. she makes a table to determine how much money she would earn for different values of t. she selects 5 as a value for t.

what is the corresponding table entry for l?

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 would need to see the dot plot : )
