Solutions are 2, odd and m - n

Step-by-step explanation:

This is because the sum of two even integers will be even, and so it will always be divisible by 2.

Example: Sum of 4 + 6 = 10 which is divisible by 2.

This is because the product of an odd integer and an even integer is even, and if you add 1 to the product the result will be odd.

Example: Let m be 7. Then 2m + 1 = 14 + 1 = 15 which is odd.

This is because the difference between an odd and an even integer will always be odd.

Example: Let m be 6 and n be 3, then m - n = 6 - 3 = 3 which is odd

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".

the anwser is d) 75°
