The expression (3x - 1)4 is expanded and simplified. which monomial listed below is a term in the result? a.-4x3 b.-27x3 c.-54x3 d.-108x3

-108x^3

Step-by-step explanation:

(3x - 1)^4

Expand the given expression and simplify it

(3x-1)(3x-1)(3x-1)(3x-1)

Use FOIL method to multiply (3x-1)(3x-1)

9x^2-3x-3x+1

9x^2-6x+1

Now multiply (9x^2-6x+1)(9x^2-6x+1)

81x^4 -54x^3+9x^2 -54x^3+36x^2 -6x+9x^2-6x+1

Combine like terms

81x^4 - 108 x^3 + 54 x^2 - 12 x + 1

-108x^3 is listed in the result

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
