Answer:
102 gallons of 55% antifreeze
68 gallons of 80% antifreeze
Step-by-step explanation:
55% antifreeze: x
80% antifreeze: y
x + y = 170 ===> -.55(x + y = 170) ===> -.55x - .55y = -93.5
.55x + .80y = .65(170) ===> .55x + .80y = 110.5
________________
add the two equations to eliminate a variable: 0.25y = 17
divide by 0.25 to isolate y: y = 68
substitution to find x:
x + y = 170
x + 68 = 170
x = 102
Answer:
2x^3 + x^2 - 9x + 6
Step-by-step explanation:
(2x^2 + 3x - 6)(x - 1)
2x^3 + 3x^2 - 6x - 2x^2 - 3x + 6
2x^3 + x^2 - 9x + 6
