Select the factored form of the expression. If
it cannot be factored, select "already in
factored form."
49x² + 64y?
Click on the correct answer.
already in factored form (7x + 8y)(7x + 8y)
(7x + 8y)(7x -8y)
49(x² + y2)

This expression is already in factored form

Step-by-step explanation:

There are no way of factoring this.

Hope this helps :)

(7x+5y)(7x+5y)

since it can not be factored.

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
