Answer:
-6x-4
Step-by-step explanation:
Answer: The required simplified answer in standard form is 
Step-by-step explanation: We are given to multiply the following polynomials and write the answer is standard form :

To multiply the given polynomials, we need to multiply each term of one polynomial to each term of the other polynomial.
From (i), we have

Thus, the required simplified answer in standard form is 
5 x 7 because if 5 is the width is 25 then 18 minus that is 7 and 7x5 = 35
