A geometric transformation is described algebraically as shown below. (x, y) → (3x,3y)
Which BEST describes this transformation?
A. A translation 3 units up and 3 units to the right
B. A translation 3 units down and 3 units to the left
C.
A dilation with a scale factor of 3 that results in an enlargement
D. A dilation with a scale factor of 3 that results in a reduction

- 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

other answer is correct. i had used the radius of the radius somehow. a website:

c

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
