Suppose that you want to solve a bunch of independent quadratic equations all at the same time, each solving the equation: ax2+bx+c = 0 You can do this in your code if you allow the coefficients to be arrays instead of scalars. Modify your script from exercise 1 to solve for quadratic equations having: a = [1 1 1]; b = [-5 -7 3]; c = [6 6 -4]; What are the three independent quadratic equations that are represented here? What are the solutions? Does your MATLAB script find the correct solutions?

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
