Answer:
Step-by-step explanation:
The first step is to find the multiplied out numerator and denominator, and then to simplify if possible. For the numerator, 3x*x=3x^2. For the denominator, (x+1)(x-7)=x^2-6x-7. This gives a final fraction of . Hope this helps!
120 degrees the sum of all is 720
y=-1/2x+1
y=mx+b
x < -12, so x+12 < 0
| x-(-12) | = | x+12 | = -x-12
