Answer:

-3x(x-2) (x+1)

Step-by-step explanation:

-3x^3+3x^2+6x

Factor out the greatest common factor which is -3x

-3x(x^2 -x -2)

Now factor the inside term. What terms multiply together to give you -2 and add to give you -1

-2*1 = -2

-2+1 =-1

-3x(x-2) (x+1)

If 4^x+1 = 64, then what is the value of x^4

Olin [163]

$4^{x} + 1 = 64 \\4^{x} = 63 \\ln(4^{x}) = ln(63) \\xln(4) = ln(63) \\x = \frac{ln(63)}{ln(4)}$

$(\frac{ln(63)}{ln(4)})^{4} = 79.78006702$

The value of x⁴ is equal to 79.8006702

Is − 227 in the sequence below? 13 , 7 , 1 , − 5 , − 11 ,

Papessa [141]

Answer:

Step-by-step explanation:-227 is in The sequence

13,7,1,-5,-11,.....

First term=a=13

Common difference=d=7-13=-6

Checking if -227 is in The sequence

using the formula

Tn=a+dx(n-1)

-227=13+(-6)x(n-1)

-227=13-6n+6

collect like terms

6n=13+6+227

6n=246

Divide both sides by 6

6n/6=246/6

n=41

Therefore -227 is the 41ist term Of The sequence
