Answer:
.754
Step-by-step explanation:
Percentage is based off of 1 or 100% which is equal to 1. So 50% or half of both 100% and 1 would be translated as .5 and as the percentage becomes more accurate or lengthy you add to the decimal so 53% is .53 and 53.4% is .534
x = 5, -3
x² - 15 = 2x
x² - 2x - 15 = 0
(x - 5)(x + 3) = 0
