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

The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9
<h3>How to determine the quadratic equation?</h3>From the question, the given parameters are:
Roots = (-1 - √2)/3 and (-1 + √2)/3
The quadratic equation is then calculated as
f(x) = The products of (x - roots)
Substitute the known values in the above equation
So, we have the following equation
This gives
Evaluate the products
