During strenuous work a human body generates about 2,400 btus of body heat per hour. if 7 bodybuilders are in a gym that is 20 ft × 25 ft × 12 ft lifting weights, how many btus per cubic foot do they produce in 3 hours? (to the nearest tenth) a) 2.8 btus/ft3 b) 8.4 btus/ft3 c) 33.7 btus/ft3 d) 100.8 btus/ft3

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
