6 times (5-1) = (blank times 5) - (blank times 1)
Somebody please help me i'm confused on how to do this.

Step-by-step explanation:

so you you P.E.M.D.A.S to solve for this.

SO paranthesis first 5-1 =4 so 4 times 6 = 24

then take 24 -5 it will = 19

then you do 19 times 1

your answer is 19

The blank will consist 6.

Step-by-step explanation:

6*(5-1)=(6*5)-(6-1).

here we have used the law of multipilication to solve it.

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".
