(2x-10)(x+3)+(x3+1)(x-4) what does it equal to
Solnce55 [7]

Answer:

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 <u>-30 - 4 </u>

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

STALIN [3.7K]
No that answer does not make sense because you can't have -38 owls. Understand? Message me if you don't. :)

Three students are selected at random from a class consisting of 5 freshman, 3 sophomores, and 2 juniors. Find the probability t
DiKsa [7]
There are 10 students and 3 are selected. When 1 freshmen is selected, it leaves 9 students and 2 slots. There are 72 different events because there are 9 students for the first one of those two and 8 for the other. You then have to find how many of them have 1 freshmen and 1 junior. There are 12 events were a freshmen is chosen after a junior and 12 were they are chosen before a junior. (3x4). this means that 24/72 events meat the criteria so their is a 1/3 or 33.3% chance.
