Select the expression that is equivalent to 8x3 + 512. A. 8(x+4) (x2 - 4x + 16)
B. O 8(x+4) (x² + 4x + 16)
C. O (2x + 8) (4x2 - 16x + 16)
DO (2x + 8) (4x2 – 322 +64)

Step-by-step explanation:

8x³+512

we know 512 is 8³. so: (2x)³+8³

now:

(2x+8)(4x²-16x+64)

I guess C might be the correct answer considering it may have been written wrong. because in the second braces we should do this:( (2x)²-(2x ×8) +8²) and 8²=64 not 16

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
