Answer 10

Well it's B but how did you come to that are you just guessing @nuccioreggie

Answer 11

@nuccioreggie just think about it logically, so you have the equation "6a +15"

Now you need to find one of the four equation that should equal 6a +15 using one of those on the list.

for example Answer A) 6(a+15)

Since 6 is on the outside you need to multiply it out, so you should get "6xa = 6a" and "6x15 = 90" So total you would have "6a + 90" which does not match "6a +15"



Just test yourself with all of them, and one of them should equal to the above statement

Answer 17

@nuccioreggie

Yup, because since the "3" is on the outside of the parenthesis, of "3(2a + 5)" you need to multiply this by everything inside of the "()" brackets.

hence, "3 x 2a = 6a" and "3 x 5 = 15" combine the two to equal "6a + 15"
