Triangle has side lengths 3, 4, and 5. Triangle has side lengths 6, 7, and 8.

Similar means that all sides need to have the same ratio. So you know that they're not similar because they all have different ratios. So in order to make them similar, you need to come up with the same ratio for all three sides. So all you have to do is create a ratio like 1:2 that applies to all three sides. Multiply all three sides by 2, and then you'll have 2 similar triangles.

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".
