Final answer:
The student's question regarding the measurement of AQ cannot be answered precisely without further information or context, such as a diagram or the value of x in the expression ST=4.5x.
Step-by-step explanation:
The student asked to find the measurement of AQ given that AS=3.2 and ST=4.5x. Since we have the measure of AS and a relation for ST but not ST itself, we cannot directly calculate AQ without more information or context. In real-world problems, details such as a diagram, additional relationships, or other given values are often critical to finding a solution. To answer questions about calculating lengths, one would typically add or subtract the lengths of segments if they're consecutive, or use proportions if it involves similar triangles, for example.
Without knowing the exact relationship between AQ, AS, and ST, or having a specific value for x, a precise calculation cannot be completed. However, if we were given that AQ = AS + ST, and a value for x, we could substitute and find AQ by calculating AQ = 3.2 + 4.5x and rounding to the nearest tenths based on the least precise measurement as per the significant figures rule.
