Answer:
x = (-5 ± √57) / 2
Step-by-step explanation:
x² = 8 − 5x
x² + 5x − 8 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -5 ± √(25 − 4(1)(-8)) ] / 2
x = (-5 ± √57) / 2
Answer:
It's also 52 If I got it wrong I'm so sorry but I'm good at angles
Step-by-step explanation:
Company X - 5.00-.37=4.63/.08=57
