D

D is for.. Data!
Data is the information used in a graph, cordinate plane, equations, etc. Data is usually numbers.

3x+5+7=15

The data for this is 3x, 5, 7 and 15

The data for this graph below are all the numbers within

Denominator- the denominator is the bottom number of the fraction. A way ro rememeber that is that denomenator starts with a D so does down.

** Distributive Property- **

** The distrubitive property distributes numbers //outside// the parethenses to the numbers //inside// the parentheses. **

​ **Examples:**

2(3 + 4)

2 x 3 = 6

2 x 4 = 8

Then you add 6 and 8 together, and there is your answer, 14!

 * || 3/5 = 60% || then, || 5*.60 = $2 ||

 Data- Information 
 * Divisible**- if something is divisible by another number, the answer has no remainder or decimal in it.
 * Ex. 6 / 2 = 3​ an example of a remander is here. 7/2 = 3 R 1 R stands for reamander. **

Distance formula: The distance between two points, with coordinates (x2,x1) and (x2,y2) is given by d= the square root of (x2-x1) to the power of 2 + (y2-y1) to the power of 2.
