Ok, so I didn't pay attention at math at all. Then we took a test and i got a 8/50 O_O!! Now today I have to take a retake in about 30 min.. & I'm having trouble learning this stuff on my own (But I'm sure it's super easy) So I'll give you examples from my last test and can you please explain how to do the problem and how you got that answer? The teacher said it's on distributive property mostly.
Simplify the expression:
5(k -7) - k - 7
-
4x + 8x
-
6a - 9a + 4a
-
6(x+6) - 10 (x -4)
Use the distributive property to rewrite the expression:
5 (x + 7)
