Use the pattern To Find following numbers following numbers.
A. 66,66,667^2
B. 6,66,66,667^2

- 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

114,240

is the anwser to this question

this is a math question that is a riddle in which you can only discover the answer by cracking the given equations and each answer has the corresponding letters. nonetheless, the solution to this is the scientist created  an exact duplicate of himself because he was just cloning around.

$20 bought 16 songs

therefore each song costs $20/16 = $5/4 = $1.25

so:

2 songs would cost 2 * $1.25

3 songs would cost 3 * $1.25

songs would cost x * $1.25

since renata started with $20, then her balance (y) after buying x songs would be:

y = 20 - 1.25*x

well we can use $ left as the y axis and the amount songs purchased as the x axis.   first we are going to divide 20 by 16 to get 1.25 which means that each song is $1.25. *which means after 16 songs on the x axis the lone should be at the bottom at point (0, 0).*   your equation is y=20-1.25x if you need more information just let me know : )
