The table represents the start of the division -2x^3+11x^2-23x+20 of by x^2-3x+4 . Which terms belong in one of the shaded cells
Andrew [12]
By polynomial grid division, we start by the divisor x²-3x+4 placed on the row headings of the table and end with the quotient -2x + 5 on the column headings as given. We know that -2x³ must be in the top left which means that the first column entry is indeed -2x. So the row and column multiply to -2x³. We use this to fill in all of the first column, multiplying -2x by the terms of the row entries.
               -2x      5
      x²      -2x³
     -3x      6x²
      4       -8x
We now got 6x² though we want 11x². The next quadratic entry must then be 5x² so that the overall sum is 11x². Multiplying 5 by the terms of the row entries, we fill in all of the second column:
               -2x      5
      x²      -2x³     5x²
     -3x      6x²    -15x
      4       -8x      20

The bottom and final term is 20, which is our desired answer and we can read the quotient off the first row: 
     -2x³ +11x² - 23x + 20 / x² - 3x + 4 = -2x + 5
We have calculated for all the terms that belong in table, therefore, the terms 5x² and 6x² belong in the shaded cells.

Answer:

  -19/7

Step-by-step explanation:

If the variation is direct, any multiplier of the m-value will also multiply the f-value.

 old value × 1/7 = new value

 m: 14 × 1/7 = 2

 f: -19 × 1/7 = -19/7

The new value of f is -19/7.

A: P = 2L + 2W solve for W<br><br>B: C = 5/9(F - 32) solve for F​
aliya0001 [1]

Answer:

A. P/2 - L = W

B. 9/5C + 32 = F

Step-by-step explanation:

A. P = 2L + 2W

P = 2(L+W)

P/2 = L + W

(P/2)-L = W

B. C = 5/9(F - 32)

9/5C = F - 32

9/5C + 32 = F
