Simplify (x − 4)(x2+ 5x + 2). x3 + x2 − 18x − 8 x3 + x2 + 22x − 8 x3 + 9x2 − 18x − 8 x3 + 9x2 + 22x − 8

Answers

Answer 1
Answer:

Answer:

{x}^(3)  +  {x}^(2)  - 18x - 8

Step-by-step explanation:

The given expression is:

(x - 4)( {x}^(2)  + 5x + 2)

We need to expand using the distributive property:

x( {x}^(2)  + 5x + 2) - 4( {x}^(2)  + 5x + 2)

This implies that:

{x}^(3)  + 5 {x}^(2)  + 2x - 4 {x}^(2)  - 20x - 8

Regroup similar terms and simplify:

{x}^(3)  +  {x}^(2)  - 18x - 8

The first choice is correct.

Answer 2
Answer:

Answer:  A) x³ + x² - 18x - 8

Step-by-step explanation:

  (x - 4)(x² + 5x + 2)

= x(x² + 5x + 2) - 4(x² + 5x + 2)

=   x³  + 5x² + 2x - 4x² - 20x - 8

=   x³ + (5x² - 4x²) + (2x - 20x) - 8

=  x³  +       x²        +     -18x      - 8

"34" is split into "3" (stem) and "4" (leaf).Answer:

Hi!

By definition a stem-and-leaf plot each data value of the data set is split into a "leaf" (usually the last digit) and a "stem" (other digits).

First, you have to sort the data set:

34, 35, 39, 41, 42, 45, 45, 47, 48, 56, 58, 62

Second, split the numbers:

  • "34" is split into "3" (stem) and "4" (leaf).
  • "35" is split into "3" (stem) and "5" (leaf).
  • "39" is split into "3" (stem) and "9" (leaf).
  • "41" is split into "4" (stem) and "1" (leaf).
  • "42" is split into "4" (stem) and "2" (leaf).
  • "45" is split into "4" (stem) and "5" (leaf).
  • "47" is split into "4" (stem) and "7" (leaf).
  • "48" is split into "4" (stem) and "8" (leaf).
  • "56" is split into "5" (stem) and "6" (leaf).
  • "58" is split into "5" (stem) and "8" (leaf).
  • "62" is split into "6" (stem) and "2" (leaf).

Last, complete the table for stem-and-leaf.

I need to find the letters

Answers

Answer:

w = 21

x = 13

y = -11

z = -16

Step-by-step explanation:

Matrix subtraction is simply subtracting "corresponding" values e.g. row 1 column 1 value of one matrix and row 1 column 1 value of another matrix, and so on...

Thus, w = 17 - (-4) = 17 + 4 = 21

x = 12 - (-1) = 12 + 1 = 13

y = -3 -8 = -11

z = -2 -14 = -16

These are the values of w, x, y and z , respectively.

If a loan of 5000 naira is given at a rate of 5% of 8 months find the amount

Answers

Answer:

S=5000(1+(0.05)(8)).

Step-by-step explanation:

The loan is 5000, the rate is 5% and years are 8. So the amount is 7000. To find amount we use formula, S=P(1+ni). P is 5000 which is a loan. N is a number of years and i is the rate of interest. So by putting values in the formula, S=5000(1+(0.05)(8)).
