Answer:
<h3>x^2+3x-12/(x+3)(x-5)(x+7)
</h3>
Step-by-step explanation:
<h3>D</h3>
Angle B is the linear pairs with 60°, so the size is 180-60=120°
Angle ABC is the linear pair with 120°, so the size is 180-120-60°
Angle A corresponds to angle 60°, so they are equal
Angle BAC is the linear pair with angle A and angle 70°, so 180-(60+70)=50°
Angle ACB is 180-(50+60) = 70°
<h3>Answer: so 3 goes into 12 4 times and 5 times 4 is 20.
