Answer:

3, 27 and 9,9

I'd like to see some of your own efforts here.  This is the third time you've posted two "factor completelyl" problems, without sharing what you've already done.

<span>3v^2 - 8v - 16 cannot be reduced.  Thus, your best choice to find roots is to apply the quadratic formula:

         8 plus or minus sqrt( 64-4(3)(-16) )
v = ---------------------------------------------------
                                2(3)
        8 plus or minus sqrt( 64 + 192 ) 
   = ---------------------------------------------
                                 6
         8 plus or minus sqrt(256)
    = -------------------------------------
                             6

     = 8 + 16, all divided by 6, or    8 - 16, all divided by 6

     = 4 or -8/6, or 4 or -4/3.

The factors are (v-4) and (v + 4/3).</span>

How do I do this? please help me
Dmitry_Shevchenko [17]
The ratio is 9 to 16

9/16 = x/12
cross multiply
9 times 12 = 108
16 times x = 16x
108 divided by 16 is 6.75
it would measure 12 by 6 3/4
