Beth enlarged the triangle below by a scale of 5. A triangle with a base of 4 centimeters and height of 3.5 centimeters.

She found the area of the enlarged triangle. Her work is shown below.

One-half (4) (3.5) (5) = 35 centimeters squared

What was Beth’s error?

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)
