Answer:
(4x + 7) or
(16x^2 - 28x + 49)
Step-by-step explanation:
This is the sum of cubes. If you have choices you really should list them because often the way we write answers is not in agreement with what you are given.
Step One
Factor 64x^3 and 343 into prime factors.
64x^3: 4*4*4*x * x *x
343: 7 * 7 * 7
Step Two
Factor using the sum of cubes.
(4x + 7)([4x]^2 - 7*4x + 7^2)
(4x + 7)(16x^2 - 28x + 49)

The value of the expression is 252
Step-by-step explanation:
The expression that we have to evaluate in this problem is

And we have toe valuate it for
x = 3
y = 4
In order to evaluate the expression, let's substitute the values of x and y into it:

First, we calculate the square of 3, which is:

Substituting into the expression,

Now we multiply everything and we get:
