Answer:
B
Step-by-step explanation:
The "..." at the end of B tell us that it's a repeating decimal so B is irrational. Of course, you can't use this reasoning for every repeating decimal but in this case it works.

Answer:
x = 4
Step-by-step explanation:
Given
- 8 - x = x - 4x, that is
- 8 - x = - 3x ( add 3x to both sides )
- 8 + 2x = 0 ( add 8 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Answer:
1.24 m
Step-by-step explanation:
F ∝ 1/d²
F = k/d²
Use values given to solve for k
0.006 = k/3²
k = 0.054 (I multiplied both sides by 3² in the equation above)
New equation is F= 0.054/d²
Plug in your numbers so 0.035 = 0.054/d²
0.054/0.035 = d²
You can simplify if you want so d² = 54/35
Square root both sides to solve for d
√54/35 = 1.24 m
