What is the value of the expression when n = 3?

inysia [295]

The value of expression when n = 3 is 22

Solution:

Given expression is:

$\frac{6(n^2 + 2)}{n}$

We have to find the value of expression when n = 3

Substitute n = 3 in given expression

$\rightarrow \frac{6(3^2 + 2)}{3}\\\\Simplify\ the\ above\ expression\\\\\rightarrow \frac{6(9+2)}{3}\\\\Solve\ the\ terms\ inside\ the\ bracket\\\\\rightarrow \frac{6(11)}{3}\\\\Divide\ 6\ by\ 3 \\\\\rightarrow 2 \times 11 = 22$

Thus the value of expression when n = 3 is 22

Find (w² + 1)(w³ - w + 1).

Citrus2011 [14]

Answer:

Product is $w^5+w^2-w+1$

Step-by-step explanation:

Given: $(w^2+1)(w^3-w+1)$

Simplify the product of polynomial.

It is product of binomial with trinomial.

$\Rightarrow (w^2+1)(w^3-w+1)$

$\Rightarrow w^2(w^3-w+1)+1(w^3-w+1)$ (Distributive property)

$\Rightarrow w^2\cdot w^3-w^2\cdot w+w^2\cdot 1+w^3-w+1$ (Distributive property)

$\Rightarrow w^5-w^3+w^2+w^3-w+1$ (combine like term)

$\Rightarrow w^5+w^2-w+1$

Product is $w^5+w^2-w+1$
