<p>Yesssssssss</p>
<p>So what is the final answer to the M + N question? </p>
<p>and what is the final answer to the mulch question and what letter (if possible)?</p>
<p>Its MN</p>
<p>Idk about 2nd question. If someone can provide dimensions of the plot of land he was trying to fill and specific numbers (i think 2 inches and 3 inches were part of it), it hsouldn’t be hard to figure out.</p>
<p>I think the mulch one was 17 which was answer choice b.</p>
<p>@imadropout</p>
<p>No, I’m pretty sure it’s m+n. You add exponents, not multiply.</p>
<p>The last multiple choice question on math was 8m.</p>
<p>@lookingup the polynomial one?</p>
<p>No. ‘8m’ was the answer to the last question in the math section.</p>
<p>I think that I put 4m^2. What was the question?</p>
<p>2^(n+1)= 2m. Question asked what was 2^(n+3) is terms of m?
2^(n+1)=2m can be rewritten as (2^n)(2^1)=2m. Therefore, 2^n=m.
2^(n+3)= ? can be rewritten as (2^n)(2^3)= ?. By substituting m for 2^n we would get (2^3)(m) or 8m.</p>
<p>I just plugged a number in, and 4m^2 worked.</p>
<p>I agree with Debater1996. I also got 4m^2.</p>
<p>No, answer was most definitely 8m. I plugged in numerous numbers and they worked. Besides, I think question 60 would have “more to it” than substituting values.</p>
<p>Lets take for example the value 3. 2^(3+1)=2m -> 2^4= 2m -> 16= 2m -> m= 8
Now lets substitute 3 for n in the second equation: 2^(3+3)= ? -> 2^6= ? -> 64= ?
Now if m=8, what is 64 in terms of m? The answer is 8m. You can use this same process for any other value and it will work.</p>
<p>I put 8m the only one where the math worked</p>
<p>Guys the one where l x l + l y l = -k was NOT 0.
The answer is 1. Assuming that (x,y) = (0,0), -k could be equal to -(0) which is ultimately 0. That gives you the one and only possibility.</p>
<p>What did you guys get for the mulch? I got 8 I think.</p>
<p>^it is 0 that makes no sense</p>
<p>Yes it does make sense. if (x,y) = (0,0) then l x l + l y l = -k
l 0 l + l 0 l = -(0)</p>
<p>Since K equals 0 and it works, then there is one possible solution.</p>
<p>The answer was definitely 0. The absolute value of something can never be negative, so when k is negative, there are no possible values that work.</p>
<p>See, k was NOT negative. it asked for -k which is also -(k). The negative of zero is still zero.</p>
