Multiply (2x+5)(3x\Xb2 - 2x - 4)

Multiply (2x+5)(3x² - 2x - 4)

 

Answer:

6x³ + 11x² - 18x - 20

Step-by-step explanation:

(2x+5)(3x² - 2x - 4)

Distribute them first

2x(3x² - 2x - 4) + 5(3x² - 2x - 4)

Then solve

6x³ - 4x² - 8x + 15x² - 10x - 20

Combine the like terms

6x³ - 4x² + 15x² - 8x - 10x - 20

Then solve

6x³ + 11x² - 18x - 20

What Is The Next Number? What Is The 10th Number? 0, 4, 8, 12, 16, ___

What is the next number? What is the 10th number? 0, 4, 8, 12, 16, ___   Arithmetic Sequence Finding for the next number The 10th number of the sequence 0, 4, 8, 12, 16, ____ is 36. Solution: Given the following: a₁ = 0 a₂ = 4 a₃ = 8 a₄ = 12 a₅ = 16     2. Find the difference between the second term and the first term. d = a₂ – a₁ d = 4 – 0 d = 4     3. Using d = 4, find the 10th term. a_n = a₁ + (n - 1) d a₁₀ = 0 + (10 – 1)4 a₁₀ = 0 + (9)4 a₁₀ = 0 + 36 a₁₀ = 36     4. Therefore, the 10th term of the sequence is 36 . Definition:        An arithmetic sequence is a sequence of numbers such that the difference of any two consecutive terms of the sequence is a constant. While an arithmetic series is the sum of the terms of the arithmetic sequence.
