Line ac and ray bq are perpendicular

the complement to cqd measures 150°.

hint: complement means both angles together make 90 degrees.

true or false.

(a.) true

(b.) false.

B. It would have to be false if both angles together =90. Bc just one of the angles =150. Which is more than 90

- 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
