Step-by-step explanation:
Answer:
-16t² + 13.4t + 120
= ( t-3.189)(t+2.352)
t = 3.189s or t = -2.352s (ignore)
ignore -2.352s because time cannot be in negative form
0.45 x 0.1 = 0.045 is the correct answer. Hope I helped.
Divide 24 by 3 to figure out how many cubes are in 1 step (24/3=8). Now divide 84 by 8 to figure out how many steps he built with 84 cubes (84/8=10.5). Ron's second staircase has 10 and a half steps :)
