Answer: No hate to the person above the they got their answer wrong. I think the right answer is 1.2 x 10^5 lbs.

Explanation:

To find the total weight of the two animals, we need to add their weights together. The weights are given as 5.36 x 10^4 lbs. and 6.2 x 10^4 lbs.

To add these numbers, we add the coefficients and keep the same exponent.

5.36 + 6.2 = 11.56

So, the sum of the coefficients is 11.56. Now, we need to express this number in scientific notation with the correct number of significant digits.

Looking at the given options, we can see that only option 4, 1.2 x 10^5 lbs, has the correct number of significant digits (2 significant digits). The other options have more significant digits, which means they are not rounded correctly.

Therefore, the total weight of the two animals is approximately 1.2 x 10^5 lbs.
