Answer:
The 59th Presidential Inauguration will take place on January 20, 2021. There have been many cold ceremonies, as well as warm ceremonies and even some snowy ceremonies.
Step-by-step explanation:
5x means that 5 should be multiplied by the value of x
Every time a variable is touching a number it means it’s multiplying
5x + 8 = ?
If x = 9, you would multiply 5 and 9 which is 45. You then add 45 and 8
45 + 8 = 53
Therefore 5x + 8 = 53
Hope this helps you! :)
Answer:
cool thats nice
Step-by-step explanation:
Coefficients are added together because they are like terms, this can be proven with the distributive property. For example, x(2x+x)=2x^2+x^2=3x^2.
The commutative property of addition and the associative property demonstrate this.
The word "commutative" comes from "commute" or "move around", so the Commutative Property<span> is the one that refers to moving values around.

The associative property<span> states that you can add or multiply regardless of how the numbers are grouped. </span>
