10 liters to gallons is 2.6 gallons.
First positive number (x) = x
Second positive number (y) = x+3
Product: 180 = x · y
180 = x · (x + 3)
180 = x² + 3x
0 = x² + 3x - 180
0 = (x + 15)(x - 12)
0 = x + 15, 0 = x - 12
x = -15, x = 12
x = -15 is NOT a positive number so it can be disregarded.
Answer: 12
-63/50
I think this is what you mean by simplest fom
Z / -4 < 2....multiply both sides by -4, cancelling out the -4 on the left. And dont forget to change the inequality sign because of multiplying by a negative.
z > 2 * -4
z > -8
