Final answer:
The value of h(t+4) given h(t) = 2t × 3t is found by substitution, leading to 2(t+4) × 3(t+4), which is Option A.
Step-by-step explanation:
To find the value of h(t+4) when given that h(t) = 2t × 3t, we simply replace 't' in the function with 't+4'. So, h(t+4) would be calculated as 2(t+4) × 3(t+4). Therefore, the correct answer is Option A: 2(t+4) × 3(t+4).
