Frank and Lynn are co-workers getting paid the same salary. They both decide to quit their jobs and start going to school on the same day. Frank gets a degree after just 18 months and spends $6,500 dollars on his education. Lynn only spends $3,500, but it takes her 2 years to get her degree. Assuming that they each will make $6,000 more per year after graduating, which of the following is true?

A, Frank will recover his investment at an earlier date than Lynn.

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".

homozygous. one is homozygous, while two is heterozygous.
