Citrus2011 [14]

Answer:

48

Step-by-step explanation:

Here, the sides are in proportion.

⇒ \frac{24}{k} = \frac{32}{64}

⇒ \frac{24}{k} = \frac{1}{2}

⇒ k = 24 × 2

⇒ k = 48

5x³+8x²-7x-6
Lady_Fox [76]

Answer:


Step-by-step explanation:

Whether we divide using long division or using synthetic division, the rule is the same:  If, after division, there is no remainder (i. e., the remainder is zero), the divisor binomial is a factor or the associated root is indeed a root/zero/solution.

Divide 5x³+8x²-7x-6 by (x+2) using synthetic division.  Use the divisor -2 (which comes from letting x+2 = 0):

      --------------------------

-2   /    5    8    -7    -6

                -10    4     6

     ------------------------------

          5      -2    -3    0          Since the remainder here is 0, we know that

                                               -2 is a root of 5x³+8x²-7x-6 and that (x+2) is

                                                a factor of 5x³+8x²-7x-6.


Now check out the possibility that (x+1) is a factor of  5x^3 + 8x^2 - 7x - 6:

Use -1 as the divisor in synthetic division:    

        --------------------------

-1   /    5    8    -7    -6

                -5   -3     10

     ------------------------------

          5      3   -10    4        

Since there is a non-zero remainder (4), we can conclude that (x + 1) is NOT a factor of the given polynomial expression.
