Fireworks are fired from the roof of a 100 foot building and travel 84 feet per second. The equation h (t) = -16^2 +84t + 100 models the height (h) of the fireworks at any given time (t) seconds. How long are the fireworks in the air?

With this question substitute t=3 and t=5 to determine if the two expressions are equivalent. 4(t + 3) 4t+12 which statements are true? check all that apply. a. the value of both expressions when t =5 is 32. b. the two expressions are not equivalent. c. the value of both expressions when t=3 is 15. d. the value of both expressions when t=5 is 23. e. the two expressions are equivalent. f. the value of both expressions when t=3 is 24.
