Answer:343 m
Step-by-step explanation:
Given
launch velocity of object is 
height of Platform 
height of object is given by

For maximum height velocity of object is zero
i.e. 


Therefore after 1 sec object achieves maximum height


Pull out a 5 from the first parenthesis
(5x+15) = 5(x+3)
Pull out a 25 from the second parenthesis
(25x+75) = 25(x+3)
(5x+15) + (25x+75) = your first answer = 5(x+3) + 25(x+3)
Let x = smaller number
Let y = bigger number
y = 7x + 4
x + y = 92
x + (7x + 4) = 92
8x + 4 = 92
8x = 88
x = 11
y = 7x + 4
y = 81
X= -2 or X= 3 either one works.
