To write the multiplication expression for the given expanded form, we can multiply each term individually and add them together. Let's break it down step by step:
The first term is (7x900). We simply multiply 7 by 900 to get 6,300.
The second term is (7x80). Multiplying 7 by 80 gives us 560.
The third term is (7x7). Multiplying 7 by 7 gives us 49.
Now, we add all the terms together: 6,300 + 560 + 49.
So, the multiplication expression for the given expanded form is (7x900) + (7x80) + (7x7) = 6,300 + 560 + 49.
To match the multiplication expression with its product, we evaluate the expression:
(7x900) + (7x80) + (7x7) = 6,300 + 560 + 49.
Calculating this expression, we have:
6,300 + 560 + 49 = 6,909.
So, the product of the multiplication expression is 6,909.
Now we can match the multiplication expression with its product:
(7x900) + (7x80) + (7x7) = 6,909.
Therefore, the correct match is:
(7x900) + (7x80) + (7x7) = 6,909 is matched with B. 7,065.
