Answer:
Rewrite equation as:
x^2 + 2x +2 =0
a = 1 b = 2 c = 2
x = (-b +- sqr root (b^2 -4ac)) / 2a
x = (-2 +- sqr root (2^2 - 4*1*2) ) / 2
x = (-2 +- sqr root (4 - 8) ) / 2
x = (-2 + sqr root (-4) ) / 2
x = -1 +- i

convert both fractions to their common denominators , which is 40.
7/2/5 = 7/16/40
7/3/8 = 7/15/40
as you can see, 7/2/5 is bigger. thus the answer is > .
Answer:

Step by step explanation:
We can solve this situation by using proportions for similar right triangles:

Substitute and solve for x:
Answer:
October 10, hope this helps.
Step-by-step explanation:
If Nathan started biking on October 2nd, and he started swimming on October 5th, then since October 10 is the closest day to them that he will be swimming and biking, but also because their both even numbers so he will be biking and swimming on October 10th.
A cube has 6 sides. 2 and 5 are numbers on 2 of the cube's sides. The probability is therefore 2/6 which simplifies to 1/3 or ~33.3%
