    none I think it is either -2(-3m+5) or 2(3m-5)

    For this, you use the distributive property. Which is \[\large \sf a(b+c)=ab+ac\]

    ^ yeah that's what I mean, but I see a sign error in it unless the question was typed wrong. either the answer choice has a sign error or the question has a sign error.

    use the distributive property on -2( 5-3m)

    close ... (I mean it's right, but the variable we have is m so we need to use that -10+6m and then rearrange it to look like 6m-10

    so for -10+6m you just have to write 6m first and then -10 so it's 6m-10

    the question is asking Which of the following expressions is equivalent to 6m - 10? we have reached -10+6m which is the same thing but rearranged differently, so we have to rewrite it to see that -10+6m is the same as 6m-10

    so we can't consider that because it was asking for something similar with 6m-10 so we need the minus sign. the first one seemed to be the option but it had a + so the sign was wrng.

    it was wrong due to the sign ok... for the second one we have reached the 6m-10 but it was written as -10+6m. Just rearrange it. It's the same thing!
