Green Grass, Inc. charges an initial fee of $10 plus $12 per hour for lawn services. Their main competitor S & G Lawn Care charges an initial fee of $25 plus $8 per hour. a. Complete a table. b. Write an algebraic expression to represent each company. c. Find the solution to the system of equations graphically and algebraically. d. Explain how to determine when it would be better to use Green Grass, Inc. and when it would be better to use their competitor, S & G Lawn Care.

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".
