9. Triangles: The area of a triangle is į the product of its base and its height. If
the area of the triangle shown is given by the function A(x)=x2 + 24x, find
representations for the lengths of its base and its height (where the base is longer
than the height).

Answer 1

Answer:1.The length of a rectangle exceeds its width by 9 feet. if the length were halved and the width increased by 4 feet, the area of the new rectangle would degree by 7 square feet. Find the dimension of the original rectangle

2. The base of the triangle is 3 meters more than its height. if the area of the triangle is 189 square meters. find the base and height of the triangle.

3. Let m be a constant. suppose the function f(x)=18-MX-2x^2 has a maximum value of 225/8. Find all possible values of m.

4. Let m be constant. suppose the function f(x)= x^2+mx+52 has a minimum value of 36. Find all possible values of m.
