Step-by-step explanation:
This represents an arithmetic progression with the first term of a = 15 and common difference of d = 3.
<u>The tenth row is the 10th term:</u>
<u>The row 10 has:</u>
- a₁₀ = 15 + 9*3 = 15 + 27 = 42 seats

Answer:
1. QS and RT= 15
2. Im not positive but I think it's TQ=18 
Step-by-step explanation:
For question 1, you would do 6x+3=8x-1 and solve to get the result of x=2
Then you'd plug in 6 and get QS and RT=15
For the second one I am unsure because I wasn't positive how to solve but it seems like the side RQ might be 1/2 of TQ. Sorry if thats wrong I can try and help more if you need
