-(2x+12) (9x^2+4x-9) <br><br><br>please show all work!
Bess [88]

Answer:

108 - 30x - 116x² - 18x³

Step-by-step explanation:

We have to get the value of - (2x + 12) (9x² + 4x - 9)

Now, using the distributive property of multiplication we get

- (2x + 12) (9x² + 4x - 9)

= -[2x (9x² + 4x - 9) + 12 (9x² + 4x - 9)]

= -[(18x³ + 8x² - 18x) + (108x² + 48x - 108)]

= -[18x³ + 116x² + 30x - 108]

= 108 - 30x - 116x² - 18x³ (Answer)

A meuseum had x visitors on friday. On Saturday it had 150 more visitors than it did on friday. The total number of visitors on
ANTONII [103]

Answer:

75 people.

Step-by-step explanation:

If Friday is x, then Saturday is 150 + x. The number of people on Sunday then is (Friday + Saturday)/2, thus (x + (150 + x))/2. This then simplifies to (x + 150 + x)/2 ---> (2x + 150)/2 ---> 2x/2 + 150/2 ---> x + 75. So, Friday is x and Sunday is x + 75, to find out how many more visitors the museum have on Sunday than Friday, you subtract the two numbers. (x + 75) - x = 75.
