First, find the prime factorization of both numbers.
378/2 = 189
189/3 = 63
63/3 = 21
21/3 = 7
7/7 1
378 = 2 * 3^3 * 7
132/2 = 66
66/2 = 33
33/3 = 11
11/11 = 1
132 = 2^2 * 3 * 11
For the GCF, choose the common factors with lower exponent.
378 = 2 * 3^3 * 7
132 = 2^2 * 3 * 11
From 2 and 2^2 choose 2.
From 3 and 3^2 choose 3.
7 and 11 are not common, so do not choose them.
GCF = 2 * 3 = 6
From the 3100 weekday bus traveler, 310 travelers will be
asked by the sales person. And for every 2.685 traveler questioned, a traveler will
say yes. So there will be 115 bus travelers that will use a laptop computer
while travelling.

Answer:
I'm not sure. but igs there similar because they both have 2 corresponding angles
Answer:
x = 4 ± 
Step-by-step explanation:
Given
(x - 12)(x + 4) = 9 ← expand the left side using FOIL
x² - 8x - 48 = 9 ( ad 48 to both sides )
x² - 8x = 57
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 57 + 16
(x - 4)² = 73 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ±
