For this case we have the following expression:

To find the product, we apply distributive property that states:

So:

ANswer:

B. Each side of a square is equal. So every side is 5. Formula for area is length x width. So multiply 5 and 5. Answer is 25.
Answer:
17ft
Step-by-step explanation:
5*2 + 3.5*2=17
Answer:
21 feet
Explanation:
Using pythagorean theorem to find the length of the added length of the bottom.
A^2+B^2=C^2 or 4^2+B^2=5^2 or 16+B^2=25
25-16=9 so B^2 is 9 and the square root of that is 3 so B is 3. Then you add 15+3+3 to get 21.
35/7=5
your mean is 5
hope this helps
