Why does the blood go from the lungs to pick up oxygen and then return back to the heart to be pumped around the body ? Why can't it just get out of the lungs from the first pump and then pick up an artery and go around of the body instead of returning ?
2(n-5) = 4 (n+2) Solve the equation is the answer -0.3 ? 2(n-5) = 4 (n+2) Solve the equation is the answer -0.3 ? If the intent of 4 (n + 2) is 4 times (n + 2), Expanding, 2n - 10 = 4n + 8 Therefore, 2n = -18 making n = -9. If the intent of 4 (n + 2) is 4 + (n + 2), n = -9 If ...
