The sum of a number and 15

Mathematics
1 answer:
ollegr [7]3 years ago

Answer:

x + 15

Step-by-step explanation:

The problem is in word form. Write the problem in <u>algebraic form</u>, which means using numbers and symbols (like + - ÷ x).

Take the key word:

'sum' - This means the answer when you <u>add numbers</u>. To add you use the + <u>plus sign</u>.

The sum of a number and 15 means adding a number and 15.

There is no equal sign because the question does not say "equals" or "is".

<u>Choose a variable</u> to represent "a number". I will choose the letter 'x'. Add 15 to 'x'.

x + 15

1. It is easier to apply it to real-world situations once you have learned to construct geometric figures using compasses and straightedges.

2. Constructing geometric figures yourself also helps you understand the material and learn easily.

3. There is more accuracy and it is easier to prove your accuracy in your own constructions.

I hope this helps :)

<h3>What are 3-D shapes?</h3>

3-D shapes (short form of 3-Dimensional shapes) are shapes that have width, length and height

<h3>How to determine the 3-D shape?</h3>

The coordinates are given as:

(0, 0), (-3, -4) and (-3, 0)

When the above coordinates are plotted on a coordinate plane and the points are connected;

We can see that the points form a right-triangle

See attachment for the shape

As a general rule

Rotating a right-triangle across the x-axis would form a cone

Hence, the 3-D shape would be created if the figure was rotated around the x-axis is a cone
