3. A regular pentagon has a perimeter of 10x + 15. What is the length of che side?
Ivan

Answer:

C

Step-by-step explanation:

A pentagon has 5 sides. Given that it is a regular pentagon, these 5 sides are equal.

The perimeter is the total length of all the sides of the pentagon. Since these 5 sides are all equal, we can divide the perimeter by 5 to obtain the length of a side of the pentagon.

Perimeter= 10x +15

Length of each side

= (10x +15) ÷5

= 2x +3

In scientific notation, how can you tell if it is less than or greater than 1? Explain
svlad2 [7]

Answer: See below

Step-by-step explanation:

In scientific notation, you can tell that it is greater or less than 1 by looking at the exponent. The scientific notation looks like _.__×10⁻. Note: The little lines are blanks for you to fill in. The dot at the bottom is a decimal.

If the exponent on top of 10 is positive, you are moving the decimal to the right side, making the number greater.

If the exponent on top of 10 is negative, you are moving the decimal to the left side, making it smaller and smaller.

By those statements, you can tell if a number is greater or less than 1 by looking at the exponent.
