4. what is the ratio of the number of prime numbers between 1-25 to the number of composite number between 1-25.

5. the ratio of the lengths of the sides of a triangle is 3: 4: 5. if the perimeter of the triangle is 216cm, what is the measure of the longest side?

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".

there is no answer sorry!

step-by-step explanation:

i think you would have to divide the money he had saved, which is $2,000 by the time he plans on exercising which is 40 hours, and the answer you get should tell you the answer to your question.

show us the triangle so we can answer it
