Answer:
Step-by-step explanation:
- A) x⁶ + 27y⁹ = (x²)³ + (3y³)³ - sum of cubes
- B) 3x⁹ - 64y³ - the first term is not a cube
- C) 27x¹⁵ - 9y³ - the second term is not a cube
- D) 125x²¹- 64y³ = (5x⁷)³ - (4y)³ - difference of cubes
Correct option is the last one

Answer:
252
Step-by-step explanation:
t50 = t1 + (n - 1)(d)
= 7 + (50 - 1) (5)
= 7 + (49)(5)
= 7 + 245
= 252
A = 11, b = 7
You just needed to multiply the terms together
Answer:
x = -2
x = 8
Step-by-step explanation:
Excluded values are the ones which make the denominator zero
3x² + x - 10
3x² + 6x - 5x - 10
3x(x + 2) - 5(x + 2)
(x + 2)(3x - 5)
x² - 6x - 16
x² - 8x + 2x - 16
x(x - 8) + 2(x - 8)
(x - 8)(x + 2)
[(x + 2)(3x - 5)] ÷ [(x - 8)(x + 2)]
(3x - 5)/(x - 8)
So excluded values are 8, -2
