a triangle was dilated by a scale factor of 2. if cos a = 3/5 and FD measures 6 units, how long is DE?

Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

Solve the system by the elimination method. x + y - 6 = 0 x - y - 8 = 0 when you eliminate y , what is the resulting equation? 2x = -14 2x = 14 -2x = 14

To solve the system of equations below, pedro isolated the variable y in the first equation and then substituted it into the second equation. what was the resulting equation? { 5y=10x {x^2+y^2=36
