Somebody help me please whoever answers first get it thanks and 11 points

time 0 1. 2. 3.

distance. 0. 60. 120. 180.

1.time and distance are the two main quantity.

2. distance depends on time

3.time

4. hours minutes seconds

5.distance miles metres kilometers

6.Time is always the independent variable. The other variable is the dependent variable (in our example: time is the independent variable and distance is the dependent variable).

7 multiplicative

8.miles per hours

9.rate= distance/time

rate*time=distance

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".
