Step-by-step explanation:
<u>Area of trapezoid</u>
Given a trapezoid shape whose parallel sides measure b1 and b2 and whose height (perpendicular to the base) is h, then the area of the trapezoid is given by

The dulcimer has the following dimensions


and height h
Thus

Operating


Is the required polynomial
Step 1: Isolate the absolute value expression.Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.Step 3: Solve for the unknown in both equations.Step 4: Check your answer analytically or graphically.
Answer:

Step-by-step explanation:
We can use the point-slope form given by:

Where <em>m</em> is the slope and (x₁, y₁) is a point.
So, we will substitute -2 for <em>m</em> and (5, 2) for (x₁, y₁). This gives us:

Simplify:

Distribute:

Add 2 to both sides. Hence, our equation is:
