Divide x^3+2 by x+1<br> long division<br> ppleeease! :)
anzhelika [568]

     Long division:   (x³ + 2)  ÷  (x + 1)


                                        <u>    </u><u>x² –  x  +  1   </u>
      x³ + 0x² + 0x + 2      |    x  +  1
   <u>– x³ –   x²</u>    ⋮       ⋮
          –   x² + 0x     ⋮
          <u>+   x² +   x</u><span>     ⋮</span>
                    +  x + 2
<span>                   </span> <u>–  x – 1</u>
                            + 1


         Quotient:   Q(x) = x² – x – 1;
  
     Remainder:   R(x) = + 1.


I hope this helps. =)

Which of this fraction are greater then1/2 but less then 3/4 .7/8 .2/5 .1/3 .5/8 .3/6
avanturin [10]

Answer: 7/8


Step-by-step explanation:

think of each faction as a pie or pizza.

each one will have the number of slices as the bottom number of the fraction.

now shade in the top numbers and see if it more than your 1/2

you will see 7/8 is the answer since it will be one piece left from being complete or "gone"

hope this helped angel!!
