Final answer:
The position x at time t is given by the equation x(t) = 7t + 32 meters. To find the position at 12.0 seconds, substitute t = 12 into the equation to get x(12.0 s) = 116 meters.
Step-by-step explanation:
From the initial information provided, the student appears to be working on a problem related to kinematics or possibly physics, where they are trying to calculate the position x at a specific time t. It looks like part of the confusion in the question may stem from typographical errors or improper formatting, which suggests that the question is about finding the value of x from a given equation of motion.
However, from the details available, we can see that the position x(t) has been determined to be 7t + 32 meters. Thus, to find the position x at 12.0 seconds, we plug in t = 12.0 into the equation to get x(12.0 s) = 7(12) + 32 = 116 m.
