Answer:
17-1/4y
Step-by-step explanation:
Answer:
B=fh
Step-by-step explanation:
I think?
Basically divided by b to get h over b and then times by h to get b=fh (you want to be get on its own)
A a dilation and reflection
dilation will make bigger or smaller therefore it cannot be congruent
As your question is stated, there is no answer!
I'm going to assume the polynomial you meant is:

To create a perfect square trinomial, take half the coefficient of x and then square it.

In all problems like this, you want to square half the coefficient of x -- always half.
