Polynomials can have double roots, in fact they're pretty common. if you get a reasonable zero it costs very little time to try it again for a double root. answer is the second choice
Answer:
18.86 feet
Step-by-step explanation:
One rotation of the tire is equal to the circumference of the tire
The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where
π = 22/7
d = diameter
The size of one revolution = 2 x 22/7 = 44/7 feet
The distance covered in one rotation of the tire is 44/7 feet
The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet
Answer:
B
Step-by-step explanation:
Answer:
1 1/2
Step-by-step explanation:
1*6=6
6/4=1.5
1.5 1 1/2
Let the number be 'x'
Since, the product of number and 4 less than twice that number is 336.
![x \times [(2 \times x) -4] = 336](https://tex.z-dn.net/?f=x%20%5Ctimes%20%5B%282%20%5Ctimes%20x%29%20-4%5D%20%3D%20336)
![x[2x -4] = 336](https://tex.z-dn.net/?f=x%5B2x%20-4%5D%20%3D%20336)


Now, we will split the middle term, we get



So, 
So, x = 14 or x = -12
Therefore, the negative number is '-12'.
