(2x-10)(x+3)+(x3+1)(x-4) what does it equal to

Step-by-step explanation:

Use FOIL method.

(2x - 10)(x + 3) = 2x*x + 2x*3   + (-10)*x   +   (-10)*3

                       = 2x² + 6x - 10x - 30      {Combine like terms}

                      = 2x² - 4x - 30

(x³ + 1)(x - 4) = x³*x   + x³ *(-4) + 1*x + 1*(-4)

                   =  x⁴ - 4x³ + x  - 4

(2x - 10)(x +3) +(x³ +1)(x - 4) = 2x² - 4x - 30 +  x⁴ - 4x³ + x  - 4

                           Combine like term

                                            =  x⁴ - 4x³  + 2x²  - 4x + x -30 - 4

                                            = x⁴ - 4x³  + 2x² - 3x - 34

15 batches are the most you can make

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
