Answer:

x³ -x²-30x+72

Step-by-step explanation:

→ ( x - 3 ) ( x - 4 ) ( x + 6 )

[ expand and open brackets ]

→ ( x² -4x -3x + 12 ) ( x + 6 )

[ simplify ]

→ ( x² -7x + 12 ) ( x + 6 )

[ expand ]

→ x³ +6x² -7x²  - 42x + 12x + 72

[ simplify/ final answer ]

→ x³ -x² -30x +72

0.29m + 10= 0.35m. What is m
ehidna [41]

0.29m+10=0.35m

0.29m-0.29m+10= 0.35m-0.29m

10=0.06 m

Divide by 0.06 for 10 and 0.06

10/0.06= 0.06/0.06 m

m= 166.66666

Answer is m = 166.66666- the number 6 continues

A pair of dice is rolled. Find the probability for P(not 2 or not 12)
irakobra [83]

Answer:

There’s only one way to get 12 when 2 dice are tossed, both have to equal 6. There are 6 ways tossing a single die can come out (1,2,3,4,5,6), so if you toss dice, the second die could have any one of six values with each of the numbers that could result from the first toss (e.g., 1 from die 1 and 1,2,3,4,5, or 6 from die 2). So, considering there are 6 ways to fill each of two slots, there are 6 x 6 = 36 possible outcomes of tossing two dice. Only one of them equals 12, so p(12 given 2 dice tossed) = 1/36 = 0.02777777777778.
