Answer:
The answer is
Step-by-step explanation:
In order to determine the answer, we have to know about equation. In an equation, we have variables, some of them depend on the others. If we want to know the value of one variable ( the dependent variable), we have to free it in any side of the equation.
In this case, we want to know the value of "L" variable. So we free that variable to the right side of the equation.
We divide each side by "W":
We simplify the "W" in the right side:
Finally, the solution for "L" is :
Answer: b, d, e
Trapezoids are quadrilaterals (a shape with four sides) and they have two pairs of sides; one pair are parallel, and the other pair are not.
Picture shown below.
