Consider the expression –3(y – 5)2 – 9 + 7y.
which statements are true about the process and simplified product? check all that apply.

a=the first step in simplifying is to distribute the –3 throughout the parentheses.
b=there are 3 terms in the simplified product.
c=the simplified product is a degree 3 polynomial.
d=the final simplified product is –3y2 + 7y – 9.
e=the final simplified product is –3y2 + 37y – 84.

Option 'B' and 'E' are correct.

Step-by-step explanation:

Since we have given that

Simplification needs a few steps:

So, Option 'B' and 'E' are correct.

As Option 'B' says there are 3 terms in the simplified product, which is true.

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".
