Answer:

\huge\boxed{Answer\hookleftarrow}

(a + b) {}^{3}  \\  =  (a + b)  \times (a + b) {}^{2}  \\   = (a + b)(a {}^{2}  + 2ab + b {}^{2} ) \\  = a(a {}^{2}  + 2ab + b {}^{2} ) + b(a {}^{2}  + 2ab + b {}^{2} ) \\  = a {}^{3}  + 2a {}^{2} b + ab {}^{2}  + ba {}^{2} + 2ab {}^{2}  + b {}^{3}  \\  = a {}^{3}  + 3a {}^{2} b + 3ab {}^{2}  + b {}^{3}

✐<u> (a + b)³ = a³ + 3a²b + 3ab² + b³</u>

It always seems to rain on the day after July 4th.
Rina8888 [55]

Answer:

The inductive reasoning is based on A: a limited number of observations

Step-by-step explanation:

Let's say you lived until 90 years old, and took a observation on July 4th each year. Even if you lived until 90 years old, you would only have 90 observations. And inductive reasoning allows for statements to be false, so any of the 90 observations that you took can be proven false. So really, you would have only 90 observations, with any of them that could be false. A limited number of observations would be the only thing that you could base this reasoning off of.
