Let's fill in the blanks step by step.
-
An expression for the base of the triangle:
The base \( b \) is four less than three times the height \( h \). This can be expressed as:
3h - 4 -
Equation for the area of the triangle, substituting in for the base:
The area \( A \) of the triangle is given by the formula \( A = \frac{b \times h}{2} \). Substituting \( b \) with \( 3h - 4 \):
A = (3h - 4) \cdot h / 2
Since the area is given as 38 square centimeters, we write:
38 = (3h - 4) \cdot h / 2 -
The first step in solving for h:
To eliminate the fraction, the first step is to multiply both sides by 2:
Multiply both sides by 2
Combining them together, here are the finished responses:
- Expression for the base: 3h - 4
- Equation for the area: 38 = (3h - 4) \cdot h / 2
- First step in solving for h: Multiply both sides by 2
