The base of a triangle is 18 cm and its height is 7w-1 cm. Find the expression for the triangles area
1 answer:
Answer:
Area = 9(7w -1) cm²
Step-by-step explanation:
Area of a triangle is given by the expression,
Area =
From the picture attached,
Base of the triangle = 18 cm
Height of the triangle = Vertical distance of the third vertex from the base joining other two vertices = (7w - 1)
Area =
= 9(7w - 1) square cm
Therefore, expression for the area of the given triangle will be,
Area = 9(7w -1) cm²

Here we have the following rational function:
So the graph of this function is shown in the First Figure below. Let's define another function which is a parent function:
Whose graph is shown in the second figure below. So we can get the graph of f from the graph of g this way:
Step 1. Shift the graph 3 units to the left:
Step 2. Shift the graph 2 units down:
Finally, the features of the graph of f are:
The graph of this function comes from the parent function g and the transformations are:
- A shifting 3 units to the left
- A shifting 2 units down
