(3 points)
An expression for the base of the triangle: _______
Equation for the area of the triangle, substituting in for the base: ________
The first step in solving for h: ________
An expression for the base of the triangle: 3h - 4
Equation for the area of the triangle, substituting in for the base: (3h - 4) * h / 2 = 38
The first step in solving for h: Multiply both sides of the equation by 2 to get rid of the fraction.
