Answer 3

To calculate the product of (3.8 + 5.2) and (3.8 - 5.2), you can use the distributive property, which states that a*(b + c) is equal to ab + ac. In this case, let's break it down step by step:

(3.8 + 5.2) * (3.8 - 5.2)

First, calculate the values inside each set of parentheses:

3.8 + 5.2 = 9.0 3.8 - 5.2 = -1.4

Now, you have:

9.0 * (-1.4)

Finally, multiply these two values together:

9.0 * (-1.4) = -12.6

So, (3.8 + 5.2) * (3.8 - 5.2) is equal to -12.6.
