Answer:

1536

Step-by-step explanation:

f(x) = 3 * 8 ^ x

x = 3

f(3) = 3 * 8 ^ 3

8^3 = 8 * 8 * 8

8^3 = 512

f(3) = 3 * 512

f(3) = 1536

(3x^2)(4x)=12x^3 is 3x^2 a factor of 12x^3
Diano4ka-milaya [45]

Answer:

(3x2 + 1) • (4x - 1)

Step-by-step explanation:

Equation at the end of step  1  :

(((12 • (x3)) -  3x2) +  4x) -  1

Equation at the end of step  2  :

(((22•3x3) -  3x2) +  4x) -  1

Checking for a perfect cube :

12x3-3x2+4x-1  is not a perfect cube

Trying to factor by pulling out :

Factoring:  12x3-3x2+4x-1

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  4x-1

Group 2:  12x3-3x2

Pull out from each group separately :

Group 1:   (4x-1) • (1)

Group 2:   (4x-1) • (3x2)

              -------------------

Add up the two groups :

              (4x-1)  •  (3x2+1)

Final result :

(3x2 + 1) • (4x - 1)

svetlana [45]

Answer:

10%

Explanation:

Use future value formula

Future Value =  Present Value ((1+r)^n)

26,600 =  20,000 ((1+r)^3

26,600/20,000 = (1+r)^3

1.33 = (1+r)^3

1.33^1/3 = 1+r

1.0997 = 1+r

1.0997 - 1 = r

r = 0.997 = 9.97% = 10% (rounded of to the nearest whole percentage)
