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
Answer:
Step-by-step explanation:
By distributive property, 8 x (14 + 7) = (8 x 14) + (8 x 7)
Looks like the answer is 72.89 degrees, which is roughly equal to 73 degrees.
