<h3>What is meant by addition?</h3>

Combining two or more numbers or quantities to generate a sum is known as addition in mathematics. One of the four fundamental operations of arithmetic, along with addition, subtraction, multiplication, and division, it is often denoted by the sign "+."

Addition is a key concept that is taught to children at an early age and is utilised in a number of everyday settings such as shopping and banking. It is a crucial tool for tackling increasingly difficult issues in disciplines like engineering, physics, and finance. For example, a telephone company is asked to provide service to a customer whose house is located in the forest, 900 feet away from the road along

Mental computation, pencil and paper, and calculators are only a few of the techniques that may be used to do addition. First, arrange the digits in columns, starting with the ones place, before adding two numbers.

How to solve?

To provide service to the customer in the forest, the telephone company will have to run a phone line 900 feet through the forest at a cost of $35 per foot, for a total cost of 900*$35=$31,500.

Additionally, the company will have to run the line 4,200 feet down the road at a cost of $20 per foot, for a total cost of 4,200*$20=$84,000.

In total, the cost to install the phone line for the customer in the forest will be $31,500+$84,000=$115,500.

That is a simple polynomial addition:
(7w3-4w+3)+(5w3-3w-3)
= <span>(7w^3 - 4w + 3) + (5w^3 - 3w - 3)
= </span>7w^3 - 4w + 3 + 5w^3 - 3w - <span>3
= 12w^3 - 7w
= w(</span><span>12w^2 - 7</span>)

tresset_1 [31]

Answer:

A=50.27\ cm^2

Step-by-step explanation:

<u><em>The complete question is</em></u>

A circle with a radius of 3 cm sits inside of a circle with a radius of 5 cm. What is the area of the Shaded Region?

The shaded region is the area outside the smaller circle and inside the larger circle

we know that

The area of the shaded region is equal to subtract the area of the smaller circle from the area of the larger circle

Remember that

The area of the circle is equal to

A=\pi r^{2}

so

The area of the shaded region is

A=\pi [r_1^2-r_2^2]

where

r_1=5\ cm

r_2=3\ cm

substitute

A=\pi [5^2-3^2]

A=\pi [16]

A=16\pi\ cm^2

assume

\pi =3.1416

substitute

A=16(3.1416)=50.27\ cm^2
