Answer:B
Step-by-step explanation:
You can find the GCF by seeing if the number is divisible so for 9 24/9 isn’t a integer so no for 12 24 36 and 72 are divisible so it maybe the answer for 24 36/24 isnt a integer for 18 24/18 isn’t a integer
D = rt, Distances Equal
72t = 90(t-1)
90 = 18t
90/18 = t = 5hr
second car catch up to the first in 4hrs

Answer:

Step-by-step explanation:
Given
, start by squaring both sides to work towards isolating
:

Recall
and
:

Isolate the radical:

Square both sides:

Expand using FOIL and
:

Move everything to one side to get a quadratic:

Solving using the quadratic formula:
A quadratic in
has real solutions
. In
, assign values:

Solving yields:

Only
works when plugged in the original equation. Therefore,
is extraneous and the only solution is
