Answer:

See below.

Step-by-step explanation:

OB = OA + AB

AB = OB - OA

= 4x + 8y - (2x + 9y)

= 2x - y

CD = 4x - 2y

= 2(2x - y)

Therefore the vector CD has the same direction as AB (its the same line on the coordinate plane) but has twice the magnitude of AB. That is its represented by a line twice as long.).

Please answer this quick! Factor the equation

PtichkaEL [24]

2x²(a-b) + x(b-a) + 6(b-a) = 2x²(a-b) - x(a-b) - 6(a-b) = (a-b)(2x²- x - 6)=

=(a-b)(2x+3)(x-2)

6x²(a-b) + x(a-b) + 12(b-a) = 6x²(a-b) + x(a-b) - 12(a-b) =(a-b)(6x²+x - 12)=

=(a-b)(3x - 4)(2x + 3)
