Property used in the equation 9+3+1
Tju [1.3M]

Answer:

That is the<u> associative property</u>.  In addition, it doesn't matter what order you add things in, so you can "associate" any grouping of additions and get the same result:

(a+b)+c = a+(b+c)

Note that this is true for multiplication as well:

(a*b)*c = a*(b*c)

algol13

Answer:

A = 3

Step-by-step explanation:

Given

(5x² + 3x + 4) - (2x² + 5x - 1)

Remove the parenthesis from the first and distribute the second by - 1

= 5x² + 3x + 4 - 2x² - 5x + 1 ← collect like terms

What is the sequence for 6,12,18,24
scoundrel [369]

Answer:

an =6n

Step-by-step explanation:

6,     12,      18,     24

Take the 2nd number minus the first number,  3rd minus the second, etc

12-6  =6

18-12 = 6

24-18 =6

The common difference is 6

The formula for an arithmetic sequence is

an =a1+d(n-1)

 where a1 is the first term

  d is the common difference

 n is the term number

an = 6+6(n-1)

 Distributing

     = 6+6n-6

     = 6n
