What are the solutions of the following system? StartLayout Enlarged left-brace 1st row x squared + y squared = 25 2nd row 2x + y = 25 EndLayout
(0, –5) and (–5, 5)
(0, –5) and (5, –15)
(0, –5) and (–4, 3)
(0, –5) and (4, –13)

The triangles are similar. what is the value of x? show your work.

Can some one me with these questions
