PQ + QR = PR
substituting the values we have:
8 + 7x = 9x
8 + 7x - 7x = 9x - 7x
8 = 2x
8/2 = 2x/2
4 = x
Now, for the value of PR:
9 x 4

Answer: T(x) = 18x + 65
Step-by-step explanation:
T(x) = A(x) + B(x)
T(x) = 10x + 50 + 8x + 15 [Plug in the number for A(x) and B(x)]
T(x) = 10x + 8x+ 50 + 15
T(x) = 18x + 65
