Ian invested $500 in an account paying an interest rate of 9 % compounded daily. Brianna invested $500 in an account paying an interest rate of 82% compounded
continuously. To the nearest hundredth of a year, how much longer would it take for
Brianna's money to triple than for Ian's money to triple?

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 believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

is there a question here?
