Molly rewrote the equation as shown: -5d + 11 = 8 − 3d -5d + 11 + 3d = 8 − 3d + 3d Which property did she use to rewrite the equation? Addition property of equality distributive property multiplication property of equality substitution property

A. addition property of equality.

Step-by-step explanation:

Molly added 3d to both sides of the equation.

answer: 91

step-by-step explanation:

- 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
