Four students were asked to write an expression which has terms that have a greatest common factor of 8c.

the expressions provided by the students are shown below.

Tanya

32C+16cd

Wyatt

8c-48cd

Xavier

36c-24c yang. 8c+40

Which student wrote the correct expression?

Wyatt

Step-by-step explanation:

Tanya: 32c+16cd=16c(2+d)

Wyatt : 8c-48cd=8c(1-6d)

Xavier :36c-24c =12c(3-2)

Yang: 8c+40=8(c+5)

Since the expression is required to have a GCD of 8c, Wyatt wrote the correct expression.

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 one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.
