Answer:
D. 9
Step-by-step explanation:
The segment lengths are equal, so ...
x^2 = 90-x
x^2 +x -90 = 0 . . . . . . add x-90 to put in standard form
(x +10)(x -9) = 0 . . . . . factor
The solutions are the values of x that make the factors zero: -10, 9.
The positive value of x is 9.

Answer:
30 seconds
Step-by-step explanation:
Find the least common multiple of 6 and 15.
First, write the prime factorizations.
6 = 2 × 3
15 = 3 × 5
The LCM is the product of each distinct factor.
LCM = 2 × 3 × 5
LCM = 30
They flash together at the same time every 30 seconds.
