The equation is 138=300-3x
now solve by first subtracting 300 from each side: -162=-3x
divide each side by -3: x=54

Answer:
x = 5
Step-by-step explanation:
First you distribute
9x - 21 = 24
Add 21 to both sides
9x = 45
Divide both sides by 9
x = 5

the equation is the horizontal line which parts through (-5,6), since it has no slope.
N-6/n²+11n+24/n+1/n+3
First, we need to factor the following:
n² + 11n + 24 → (n + 3)(n + 8)
n² → n * n
factor of 24 are:
1 x 24
2 x 12
3 x 8 We will use these factors. 3 + 8 = 11
4 x 6
Division involving fractions results to multiplying the first fraction to the reciprocal of the second fraction.
n-6/(n+3)(n+8) * n+3 / n+1 → n+3 is in both numerator and denominator. Cancel each other out.
n-6/n+8 * 1/n+1
n-6/(n+8)(n+1) Correct answer is Choice D.
1+3+5+7+103=119. I hope this is what you were asking for! :)
