Which expression shows a sum of three terms? (1 point) 3x 3 + x x^3 x + 3 + x

x + 3 + x

Step-by-step explanation:

3x :

This is a product of two terms, where x is any variable.

3 + x :

This is sum of two terms,where x is any variable.

x^3 :

This expresses x to the power of three. It can also be written as  (x times x times x ). Thus it is the product of three terms, where x is any variable.

x + 3 + x :

This is the sum of three terms, where x is any variable.

Thus answer is x + 3 + x

uhhh idk u yolo?

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
