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>
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
Answer:
5x^2 - 7x - 10.
Step-by-step explanation:
11x^2+2-7x-6x^2-12
Bring like terms together We get:
11x^2 - 6x^2 - 7x + 2 - 12
= 5x^2 - 7x - 10.
Answer: The answer is two
Step-by-step explanation:
Just round the decimal up
