1st. Try to make x by itself. Divide 12 on each side.
After it will look like this
x=12
1 cm^3 is equal to 1 mL so the answer would probably be 210 mL
False. it said ,"The sum of the exterior angles of a polygon is always 360 degrees<span>. ... By an inductive proof, this is </span>true<span> for all </span>polygons." that is what i think.
Rational 3667/1000
^^^^^^^^^^^
-x ---------------- 1x
7y --------------- 12y
-12x^2 --------- 8x^2
a ----------------- -2a
6a^2------------ a^2
-5x^3 ---------- 15x^3
_____________________
you just have to match the terms which have the same power.
Hope it helps ^^
