The answer is A because if you do 10*10*10 that would give you 1k and if u multiply that by 2 you get 2k
The Quotient is 8 and you would simplify if that's an option
if its not then I will tell you what else it could be
Lets get common fractions between 1/10 and 1/4, so we now have the fractions 2/20 and 5/20. After we add them we have 7/20. If 35% (7/20) of the points scored is 21, then total points scored is 60. (21 / .35)
Answer and Step-by-step explanation:




<em><u /></em>
<em><u>Distributive property of multiplication :</u></em>



→
<em><u>Now, that we know what it means let's apply it in our equation:</u></em>
<em><u /></em>
<em><u /></em>
<em><u /></em>
<em><u>Now, we simplify:</u></em>
<em><u /></em>
<em><u /></em>
<em><u /></em>
<em><u>Divide both sides by 2 in the equation:</u></em>
<em><u /></em>
<em><u /></em>
<em><u /></em>
<em><u>Simplify :</u></em>
<em><u /></em>
<em><u /></em>
<em><u /></em>
<em><u>Thus, the first correct step is option B,</u></em>

25(3x-y)²-16(5x+3y)²=25(9x²-6xy+y²)-16(25x²+30xy+9y²)=
=225x²-15xy+25y²-400x²-480xy-144y²=-175x²-630xy-119y²
