Zack is wants to make a profit of more than $300 for painting 4 identical rooms. the profit he makes is equal to the amount he is paid minus the cost of supplies. the cost of supplies is $32.40 for each room. which inequality and solution represent the dollar amount n that zack must be paid for each room, if he is to make a profit of more than $300

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".

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

x= 3^y
