A map has a scale of 1 cm : 11.5 km. Two cities are 5.5 cm apart on the map. To the nearest tenth of a kilometer, what is the actual distance corresponding to the map distance?A. 74.8 km

B. 120.8 km

C. 68.8 km

D. 63.3 km

Answers

The actual distance between the two cities corresponding to the mapdistance is 63.3 km. Then the correct option is D.

What is the distance?

Distance is defined as the length between the two points just like in the question it is the length between the two cities.

The length is calculated as:-

1 cm: 11.5 km

5.5 cm: 5.5 x 11.5 km

5.5 cm : 63.3 km

The distance between the two cities is 63.3 km.

The polynomial x3 + 8 is equal to

Answers

Answer:

$x^(3) +2^(3)=(x+2)(x^(2) -2x+2^(2) )$

Step-by-step explanation:

The general expansion of a polynomial of type $a^(3) +b^(3)$ is given as follows:

$a^(3) +b^(3) =(a+b)(a^(2) -ab+b^(2) )$

Given polynomial is $x^(3) +8$

This can be written as $x^(3) +2^(3)$ , which is of the form $a^(3) +b^(3)$ .

So we can use the general form to expand this polynomial where;

a→x

b→2

$x^(3) +2^(3)=(x+2)(x^(2) -x*2+2^(2) )$

$x^(3) +2^(3)=(x+2)(x^(2) -2x+2^(2) )$

The polynomial x3+8 is equal to (x+2)(x2-2x+4)
