Choose the correct simplification of (4x3 + 3x2 − 6x) − (10x3 + 3x2). select one: a. 6x3 + 6x b. −6x3 − 6x2 − 6x c. −6x3 − 6x d. 6x3 + 6x2 + 6x

The correct answer is option C.  -6x³ - 6x

Step-by-step explanation:

It is given an expression,

(4x³ + 3x² - 6x) - ( 10x³ + 3x²)

To find the simplified form

(4x³ + 3x² - 6x) - ( 10x³ + 3x²) = 4x³ + 3x² - 6x - 10x³ - 3x²

 = 4x³ - 10x³ + 3x² - 3x² - 6x

 = -6x³ + 0 - 6x

 = -6x³ - 6x

Therefore the correct answer is option C.  -6x³ - 6x

b) well because you get well

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
