hey Y’all I’ve been doing algebra and I was wondering if you guys can give me some tips I’ve been getting the rhythm and can get the answer easily but it’s little mistakes like instead of 3x+3 it’s 3x-3 so any tips? Thanks

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".

i pretty sure it is

not sure but it may be b, as i said i'm not sure.
