Answer:
a = 3
b = -9
c = 13
Step-by-step explanation:
3x²-7x + 9 = 2x - 4
3x² - 9x + 13 = 0
a = 3
b = -9
c = 13

Answer:
A typical mixture equation
:
x + .10(54-x) = .20(54)
x + 5.4 - .10x = 10.8
x - .1x = 10.8 - 5.4
.9x = 5.4
x = 5.4%2F.9
x = 6 L of pure acid to be combined with: 54-6 = 48 L of 10% solution
