Let the height of the tower be x feet.
Answer:
0,1
Step-by-step explanation:
x^2 − x = 0
Factor out an x
x(x-1) =0
Using the zero product property
x=0 x-1=0
Solving each equation
x=0 x-1+1 =0+1
x=0 x=1
The solutions are
x=0,1
Answer:
937.5
Step-by-step explanation:
$18.75 - 1 hour
$x. - 50hours
cross multiply the 18.75 with 50.
Set each binomial equal to zero to solve.
2n + 3 = 0
2n = - 3
n = - 3 / 2
n - 4 = 0
n = 4
So n = -3/2, 4
