The total height of the tower t and the antenna that stands on top of it a is 1729 feet. the difference in heights between the building and antenna is 279 feet. how tall is the tower.

not sure srry man

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
