Answer: the second option is the correct answer
Step-by-step explanation:
The given expression is
[3/(x - 1) - 4]/[2 - 2/(x - 1)
We would simplify the numerator first. The LCM of the numerator is
x - 1. Taking the LCM of the numerator, it becomes
[3 - 4(x - 1)]/(x - 1)
= [3 - 4x + 4]/(x - 1)
= (- 4x + 7)/(x - 1)
We would simplify the denominator. The LCM of the denominator is
x - 1. Taking the LCM of the numerator, it becomes
[2(x - 1) - 2]/(x - 1)
= [2x - 2 - 2]/(x - 1)
= (2x - 4)/(x - 1)
= 2(x - 2)/(x - 1)
The expression becomes
[(- 4x + 7)/(x - 1)]/[ 2(x - 2)/(x - 1)]
= (- 4x + 7)/(x - 1) × (x - 1)/2(x - 2)
(x - 1) cancels out. It becomes
(- 4x + 7) / 2(x - 2)
I’m not sure what you want me to solve? Because the x values for this equation would be -7 and -2
Answer:
.
Step-by-step explanation:
Since (a^m)^n=a^mn, you multiply the exponents and you get their product, which will be the new exponent of the base.Therefore, the answer would be C. Product power of a Product Property.

Answer: 29 miles (approximate)</h3>
======================================================
Explanation:
Segment AB is already given to be 19 miles long.
I'm assuming your teacher meant to ask about side BC, which is side 'a' since it's opposite angle A.
Use the law of cosines to find the missing side
a^2 = b^2 + c^2 - 2*b*c*cos(A)
a^2 = 12^2 + 19^2 - 2*12*19*cos(138)
a^2 = 843.874040417691
a = sqrt(843.874040417691)
a = 29.0495101579647
a = 29 when rounding to the nearest whole number
Side BC is roughly 29 miles long.
