Consider the relationship 3r+2rt = 18
write the relationship as a function r=f(t)

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
