<u>Sum of Cubes:</u>
a³ + b³ = (a + b)(a² - ab + b²)
Example: x³ + 8 → a=x, b=2
= (x + 2)(x² - 2x + 4)
<u>Difference of Cubes:</u>
a³ - b³ = (a - b)(a² + ab + b²)
Example: x³ - 27 → a=x, b=3
= (x - 3)(x² + 3x + 9)
<u>Difference of Squares:</u>
a² - b² = (a - b)(a + b)
Example: x² - 16 → a=x, b=4
= (x - 4)(x + 4)
Answer:
$7.44
Step-by-step explanation:
$4.96/ 2= 2.48
$2.48 X 3 = 7.44
Answer:
The are parallel lines.
Step-by-step explanation:
2x + 3y = 4
3y = -2x + 4
y = -2/3x + 4/3
10x + 15y = 2
15y = - 10x + 2
y = -10/15x + 2/15
y = - 2/3x + 2/15
Divide both sides by (a-b)
c=2/(a-b)
this is the farthest you can go without assigning a, b, and/or c actual values
