4 0

Answer:

-2x2a • (2x2 + 4b - 5)

Step-by-step explanation:

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 2xa • ((-4xb -  2x3) +  5x)

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -2x3 - 4xb + 5x  =   -x • (2x2 + 4b - 5)  

Trying to factor a multi variable polynomial :

3.2    Factoring    2x2 + 4b - 5  

Try to factor this multi-variable trinomial using trial and error  

Factorization fails

Multiplying exponential expressions :

3.3    x1 multiplied by x1 = x(1 + 1) = x2

Final result :

 -2x2a • (2x2 + 4b - 5)

In the New Orleans metropolitan area in August​ 2005, the labor force was​ 634,512 and​ 35,222 people were unemployed. In Septem
Lisa [10]

Answer:

 Unemployment (August) = 35'222/634'512 ≈ 0.0555 ≈ 5.55%

Employed (August) = 634'512-35'222 = 599'290

Labor force (September) = 634'512-156'518 = 477'994

Employed (September) = 599'290-206'024 = 393'266

Unemployed (September) = 477'994-393'266 = 84'728

Unemployment (September) = 84'728/477'994 ≈ 0.177 ≈ 17.7%

Jane made a poster that had a length: 1 2/3 of feet and a width: 5/6 of feet. What is the perimeter of her poster?
slamgirl [31]

Answer:

P   = 6 2/3 ft

Step-by-step explanation:

The formula for the perimeter of a rectangle of length L and width W is

P = 2(L + W).

Here the perimeter is P = 2(1 2/3 + 5/6) = 2(5/2 + 5/6)

                                                                  = 2(15/6 + 5/6) = 2(20/6)

                                                                  = 40/6 = 20/3

                                                              P   = 6 2/3 ft
