Which expressions are equivalent to
In x + 2 In 5 + In 1?

ln(25x)

Step-by-step explanation:

ln(x) + 2ln(5)+ln(1) = ln(x) + ln(5^2) + ln(1)

= ln(x*5^2*1) = ln(25x)

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

-6 is the correct option from the above given options
