<span>P(x) = x</span>³<span> + 5x</span>²<span> – x – 5
P(x) = x</span>²(x+5) - (x + 5)
P(x) = (x + 5)(x² - 1)
P(x) = (x + 5) (x + 1)(x -1)
The third one tells us the price is $12 per liter, that is to say, the top number is twelve times the bottom number.
.25 × 12 = $3
.7 × 12 = $8.40
2.5 × 12 = $30
3.52 × 12 = $42.24
$57.60 / 12 = 4.80 liters
Find the area of the whole rectangle and find the area of the not shaded part and then subtract them to find the are of the shaded part.
Area of whole: 10 * 6 = 60 cm²
Area of non shaded: 6 * 2 = 12 cm²
Area of shaded part:
60 - 12 = 48 cm²
