So far this season the last athlete’s fastest time is 53.18 seconds, and his average is 53.92. In this race the last athlete expects to run faster than his slowest time. Is it possible for the team to fail to meet their goal? Write an inequality and solve

m∠a is 90°

m∠b is 40°

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
