Answer:

$7x^3-2x^2-5$

Step-by-step explanation:

We need to add the two terms.

$(6x^3+3x^2-2)+(x^3-5x^2-3)$

Solving,

Combine the like terms and adding those terms

$(6x^3+3x^2-2)+(x^3-5x^2-3)\\=6x^3+3x^2-2+x^3-5x^2-3\\=6x^3+x^3+3x^2-5x^2-2-3\\=7x^3-2x^2-5$

So, the answer is:

$7x^3-2x^2-5$

Hi I would like to know how I can solve this problem.

murzikaleks [220]

The $n$ -th term is

$U_n = \dfrac14 n^2 (n+1)^2$

so the 39th term is

$U_{39} = \dfrac14 39^2 40^2 = \boxed{608,400}$

Observe that

$2^3 + 4^3 + 6^3 = 2^3 + 2^3\times2^3 + 2^3\times3^3 = 8\left(1^3+2^3+3^3)$

which suggests that

$V_n = 8U_n = \boxed{2n^2(n+1)^2}$

Apply the distributive property to factor out the greatest common factor.

podryga [215]

Answer:

12 + 20 = 4(3 + 5)

Step-by-step explanation:

The distributive property is ab + ac = a(b + c), where

a is the greatest common factor of the two terms ab and ac

Let us solve the question

∵ 12 = 1 × 12, 2 × 6, 3 × 4

∴ The factors of 12 are 1, 2, 3, 4, 6, 12

∵ 20 = 1 × 20, 2 × 10, 4 × 5

∴ The factors of 20 are 1, 2, 4, 5, 10, 20

→ Find their common factors

∵ The common factors of 12 and 20 are 1, 2, 4

∴ The greatest common factor of 12 and 20 is 4

∵ 12 ÷ 4 = 3

∵ 20 ÷ 4 = 5

∴ 12 + 20 = 4 × 3 + 4 × 5

→ Take 4 as a common factor

∴ 12 + 20 = 4(3 + 5)
