Answer:

1680 ways

Step-by-step explanation:

Permutation has to do with arrangement

If a contractor builds homes of 8 different models and presently has 4 lots to build on, the number of ways he can arrange his homes is expressed as;

8P4 = 8!/(8-4)!

8P4 = 8!/4!

8P4 = 8*7*6*5*4!/4!

8P4 = 8*7*6*5

8P4 = 1680

Hence the can arrange his homes 1680 ways

Is the answer true or false?
stira [4]

Answer:

The answer to your question is False

Step-by-step explanation:

Original division

                       \frac{3x^{3}+ 5x^{2}- 11}{2x + 1}

Process

1.- To express a division in a synthetic form we must take the coefficients of the numerator. If there is no coefficient for a variable, we write it as 0.

          3x³ + 5x² - 11 =         3    5   0   - 11

The "0" means 0x, this term is not present but we must consider it.

2.- Solve the denominator for x

                 2x + 1 = 0

                 2x = -1

                   x = -1/2

3.- Write the synthetic division

                           -1/2      3    5   0   -11
