Well, isn't that a happy little math problem we have here? To find the answer, we simply need to multiply both sides of the inequality by 3 to isolate x. So, x is greater than 45. Just like painting a beautiful landscape, sometimes all it takes is a few gentle brushstrokes to reveal the true beauty underneath.
75x3, /2, +1, x3...10 x3=30 /2=15 +1=16 x3=48 /2=24 +1=25 x3=75
The 2014 BMW X3 is 15 ft. 3 in. (183 in.) long.
The 2011 BMW X3 is 15 ft. 3 in. (183 in.) long.
The 2012 BMW X3 is 15 ft. 3 in. (183 in.) long.
The 2013 BMW X3 is 15 ft. 3 in. (183 in.) long.
10 30 15 16 48 24 25 x3 1/2 +1 x3 1/2 +1
In mathematical notation, a number cubed is written as x3. For 15 cubed, that would be 153 or (15 X 15 X 15 =) 3,375
x3 + x2 - 17x + 15 = (x - 1)(x - 3)(x + 5). Thus, the zeros are 1, 3, and -5. All three zeros are rational.
The EPA mileage estimate for the 2004 BMW X3 is 15 mpg in the city, 22 mpg on the highway.
The EPA mileage estimate for the 2006 BMW X3 is 15 mpg in the city, 23 mpg on the highway.
The EPA mileage estimate for the 2005 BMW X3 is 15 mpg in the city, 22 mpg on the highway.
(x - 3)*(x + 5)*(x - 1) = 0 (x2 - 3x + 5x - 15)*(x - 1) = 0 (x2 + 2x - 15)*(x - 1) = 0 (x3 + 2x2 - 15x - x2 - 2x + 15) = 0 ie x3 + x2 - 17x + 15 = 0
