Assuming the bike is 70 inches
70/12in = <span>5.83333333333</span>
Answer: D
Step-by-step explanation:
(3 + 2i) (3-2i) = 13
1 meter = 100 cm
85 cm
1 mm = 0.1 cm, so 400 mm = (400 x 0.1) = 40 cm
100 + 85 + 40 = 225 cm <== total length
135 is the answer because ^ they said it
Answer:
2 real solutions
Step-by-step explanation:
We can use the determinant, which says that for a quadratic of the form ax² + bx + c, we can determine what kind of solutions it has by looking at the determinant of the form:
b² - 4ac
If b² - 4ac > 0, then there are 2 real solutions. If b² - 4ac = 0, then there is 1 real solution. If b² - 4ac < 0, then there are 2 imaginary solutions.
Here, a = 6, b = -20, and c = 1. So, plug these into the determinant formula:
b² - 4ac
(-20)² - 4 * 6 * 1 = 400 - 24 = 376
Since 376 is clearly greater than 0, we know this quadratic has 2 real solutions.
