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

A clients rash measures 5cm x 4cm how much does this measure in inches

yan [13]

Given:

A clients rash measures 5 cm × 4 cm.

To find:

The measure in inches.

Solution:

We know that,

2.54 cm = 1 inch

1 cm $=\dfrac{1}{2.54}$ inch

1 cm $\approx 0.3937$ inch

Using this conversion, we get

5 cm $=5\times 0.3937$ inches

5 cm $=1.9685$ inches

4 cm $=4\times 0.3937$ inches

4 cm $=1.5748$ inches

Therefore, the measure in inches is 1.9685 inches × 1.5748 inches.
