Coleman graphed the relationship between the number of rotations of his front bike tire and the distance he traveled past a tree. Negative distance means the tree is in front of Coleman and positive distance
means the tree is behind Coleman

i dont know itanswer:

step-by-step explanation:

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".

this is answer of 144 cubic meters

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
