Answer:
D, -42 multiply 6 on both sides
A secant is a line that intersects a circle at two points.
To do this you multiply 12 by 12 to get 144. Now you want to divide 144 by 8. This gives you 18. Therefore, when y is equal to 12, x would be equal to 64.
C= 2sqrt55 or 14.83
formula= a^2+b^2=c^2
plug in
14^2+sqrt24^2=c^2
196+24=c^2
220=c^2
take the square root of each side
2sqrt55=c
No because the equation -2=10 has no solutions. But in -5x=25, x=-5, (do -5x-5 to get 25) making the equation 25=25. therefore, -5x=25 has many solutions. And the equations are not equivalent.
