8H+ + MnO4- + 5Fe2+--> 5Fe3+ + Mn2+ + 4H20
Area is 1/2 base x height. We don't know the height so let's call it h. The area is 8h/2 or 4h.
8h+7=-113 -113+7==106/8=h=-13.25 h=-13.25
How do you solve this equation 20h-40=8h+152 ?
h=7
8h - 10h = 3h + 25-2h = 3h + 25-5h = 25-h = 5h = -5
5h+11=13h-21 -5h +21 -5h +21 32=8h /8 /8 4=h
h = -5 8h - 10h = 3h + 25 -2h = 3h + 25 -2h - 3h = 3h - 3h + 25 -5h = 25 h = -5 CHECK: 8(-5) - 10(-5) = 3(-5) + 25 -40 - -50 = -15 + 25 -40 + 50 = 10 10 = 10 CORRECT
