The formula for the area of a triangle is a=1/2bh. hiro is solving the equation for h; his work is shown below. what mistake did hiro make?
a=1/2bh
2(x)a=2(x)(1/2bh)
2a=bh
2a-b=h
(x) is multiplication sign btw
hiro should have divided both sides of the equation by 2. hiro should have divided both sides of the equation by b. hiro should have added b to both sides of the equation. hiro should have subtracted 2 from both sides of the equation.
