To find the total length of the two insects, we add the lengths of the two insects together. In scientific notation, we write the sum of the lengths as (4×10−2 + 1.3×10−1) inches. Simplifying the sum, we have (4 + 13)×10−2 inches = 17×10−2 inches. Converting to decimal notation, we obtain 17×10−2 inches = 1.7×10−1 inches. Therefore, the total length of the two insects is approximately 1.7×10−1 inches.
