A car travels 150km on 12 L of gasonline. How many liters are there of gasoline needed to travel 500km

coldgirl [10]

150 = 12
150 +150 = 300 which = 24
150 + 150 + 150 = 450 which =36

the remaining 50 is 12 ÷ 3, so 4. 36 + 4 = 40.

therefore, 40 L of gasoline are needed to go 500km

1. Determine the zeros of f(x) = x3 – 3x2 – 16x + 48? Somebody explain it please?:/

inn [45]

$x^{2} - 3x^{2} - 16x + 48 = 0$

$x^{2} (x - 3) - 16(x - 3) = 0$

$(x - 3) ( x^{2} - 16) = 0$

$(x - 3) (x - 4) (x + 4) = 0$

$x = -4, 3, 4$

The zeros are: -4, 3, 4
