Answer;
x = 0.6 and x = -1.75
Step-by-step explanation:
80x2+92x−84=0
Use quadratic formula
x = (−b ±√(b2−4ac))/√2a
x = (-92 ± √(35344)) / 160
x = 95/160 and x = -280 / 160
x = 0.6 and x = -1.75
Opened or closed circle? I can help! I know inequalities

The GCF (greatest common factor) of 35 and 63 is 7.
Answer:
∠B = 17°
Step-by-step explanation:
Vertical angles are congruent, thus
5x + 7 = x + 15 ( subtract x from both sides )
4x + 7 = 15 ( subtract 7 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Hence
∠B = 5x + 7 = (5 × 2) + 7 = 10 + 2 = 17°
