The answer is in a pattern the pattern consist that 12 is what each number equals
The sum of a rational number and an irrational number is irrational." By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats.
Answer:
2.28 and 0.22
Step-by-step explanation:
2x²+1=5x
2x²-5x+1=0
this cannot be properly factorized
so let's use the almighty formula,
where a=2, b=-5, c= 1
=-(-5)±√{(-5)²-4x2x1} x 1/(2 x 2)
=5±√25-8 x1/4
=5±√17 x ¼
=(5±4.12)/4
=2.28. or. 0.22
roots=2.28 and 0.22
Answer:
2400 km
Step-by-step explanation:
distance=rate*time
d=rt
d=(800)(t+1)
d=(1200)(t)
the right sides are both equal to d so set them equal to each other
800(t+1)=1200(t)
800t+800=1200t
800=1200t-800t
800=400t
t=800/400
t=2 hours
d=1200*2
d=2400 km
