Step-by-step explanation:
Categorical data is a collection of information that is divided into groups. Categorical data can take on numerical values (such as “1” indicating Yes and “2” indicating No), but those numbers don't have mathematical meaning
Answer: I'll solve A) since there is a lot of work to be shown.
Step-by-step explanation:
A)
(x−1)³+3x(x−4)+2=x³
Use binomial theorem to expand (x−1)³
x³- 3x² + 3x - 1 + 3x(x-4) + 2=x³
Use distributive property on 3x(x-4)
x³- 3x² + 3x - 1 + 3x²-12x + 2=x³
Add like terms
x³ −9x + 1 =x³
Subtract x³ from both sides.
x³ −9x +1 -x³ = 0
Add x³ and -x³
−9x+1=0
Subtract 1 from both sides. Anything subtracted from zero gives its negation.
−9x=−1
Divide both sides by -9.
x=
1/9
