5/10x = 2/10x + 15
5/10x - 2/10x = 15
3/10x = 15
x = 15 * 10/3
x = 150/3
x = 50
2/10(50) = 100/10 = 10 in. ....shortest piece
3/10(50) = 150/10 = 15 in .....middle piece
5/10(50) = 250/10 = 25 in .....longest piece

Step-by-step explanation:
is this what your looking for? what form would you like me to answer this in?
Answer:
Graph x2 = 4y and state the vertex, focus, axis of symmetry, and directrix. ... this "algebraically" by rearranging the given equation into the conics form: ... picking y-values first and then finding the corresponding x-values for x = –y2 – 10y – 25: ... find the exact vertex, etc, I'll need to convert the equation to perfect-square form.
