Answer:
$191.70
Step-by-step explanation:
total amount spent = cost of medicine + cost of tax + cost of shipping
cost of tax = 0.05 x $180 = $9
cost of shipping 0.015 x $180 = $2.70
total cost = $180 + $9 + 2.70 = $191.70
x² + 18 = (x - 3√2i)(x + 3√2i)
Answer:
Step-by-step explanation:

15/x=3/4
times 4x both sides
4*15=3x
60=3x
divide both sides by 3
20=x
