The third term is 9
t(3)=2(3)+3
6+3 = 9
Q+P =180 so (Q is 137) p=s so (s is 43) and q = r so (r is 137)
Answer:
very easy if you make me brainliest
Use the FOIL method
First, Outside, Inside, Last
(2x -5)(x + 3)
2x(x) = 2x²
2x(3) = 6x
-5(x) = -5x
-5(3) = -15
2x² + 6x - 5x - 15
simplify
2x² + 6x - 5x - 15
2x² + x - 15
2x² + x - 15 is your answer
hope this helps
