Which expression is equivalent to 64x^3-343
In-s [12.5K]

Answer:

B:  (4x - 7)(16x^2 + 28x + 49)

Step-by-step explanation:

64x^3-343 can be rewritten as 4^3x^3 - 7^3 or (4x)^3 - 7^3.  This is the difference of two cubes.  The appropriate formula for factoring such is

       a^3 - b^3 = (a - b)(a^2 + ab + b^2).  Therefore,

our (4x)^3 - 7^3 = (4x - 7)(16x^2 + 28x + 49).  This is Answer B.

Solve the following equation <br><br> 1/x-1+1/x+2=3
disa [49]

Answer:

x = 1

Step-by-step explanation:

Solve for x over the real numbers:

-1 + 2 + 1/x + 1/x = 3

-1 + 2 + 1/x + 1/x = 1 + 2/x:

1 + 2/x = 3

Bring 1 + 2/x together using the common denominator x:

(x + 2)/x = 3

Multiply both sides by x:

x + 2 = 3 x

Subtract 3 x + 2 from both sides:

-2 x = -2

Divide both sides by -2:

Answer:  x = 1
