Answer:

b) 2(x-6)(x+9)

Step-by-step explanation:

2x^2+6x-108

Factor out the 2, common factor!!!

2 (x^2 +3x -54)

Now time to factor, what to numbers multiply to get -54 and add to get 3

6,9 look good

what combination???

9,-6 because 9-6 = 3 and 9x-6=-54

2(x-6)(x+9)

From what I'm use to you put the 2 back in by dividing the numbers but in this case you dont need to.

Max was on vacation twice as long as Jerrad and half as long as Wesley. The boys were on vacation a total three weeks. How long

mote1985 [20]

3 weeks = 21 days
Let Jerrad's vacation be X then Max's be 2X and Wesley's 4X
X+2X+4X=21
7X=21 devide by 7
X=3 so Jerrad had 3 days vacation
2*3= 6 Max had 6 days
4*3=12 Wesley had 12 days vacation
