Answer:
We want to expand the expression:
We can just do it by brute force, this is:
First, rewrite our expression as the product of two square factors:
Now we can expand each one these two factors:
That can be simplified to
Now we can replace that in our original expression to get:
Now we can expand that last product, to get:
We can simplify that to:
That is the expanded expression.
Answer:
The equation is 18h=378
h=21
Step-by-step explanation:
So first you have to set up the equation
so if she makes 18 dollars an hour the first part of the equation would be 18h
She made 378 dollars in one week so now the equation is 18h=378
The answer is h=21 because 378/18 is 21
A.you get a symmetric matrix.
you can add to a non symmetric matrix a diagonal symmetric matrix and get a symmetric one but not always and i don t know if you can get one by multiplying two non symmetric matrices.
