Answer:
28
Step-by-step explanation:
a³+b³= (a+b)³ - 3ab(a+b)
= 4³ -3×3×4 = 64-36 = 28
<span>Simplifying
8x + 336 = 336 + -3x
Reorder the terms:
336 + 8x = 336 + -3x
Add '-336' to each side of the equation.
336 + -336 + 8x = 336 + -336 + -3x
Combine like terms: 336 + -336 = 0
0 + 8x = 336 + -336 + -3x
8x = 336 + -336 + -3x
Combine like terms: 336 + -336 = 0
8x = 0 + -3x
8x = -3x
Solving
8x = -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
8x + 3x = -3x + 3x
Combine like terms: 8x + 3x = 11x
11x = -3x + 3x
Combine like terms: -3x + 3x = 0
11x = 0
Divide each side by '11'.
x = 0
Simplifying
x = 0</span>
