Distribute the 4 on the left side, what do you get?

OpenStudy (anonymous):

tbh: i dont really understand what this is , i need help but idk ?

terenzreignz (terenzreignz):

Here's an example of distribution... 3(7 + k) You just multiply 3 to each and every term in the parentheses.z.. = 21 + 3k

OpenStudy (solomonzelman):

Answer is D, since there are infinite solutions

OpenStudy (anonymous):

ah so 3x7 , & 3k ?

terenzreignz (terenzreignz):

That's for the example, now, what about in your actual question, 4(a + 3) ?

OpenStudy (anonymous):

7a ?

OpenStudy (anonymous):

terenzreignz (terenzreignz):

OpenStudy (anonymous):
