Answer: B. 12=9+3x
Step-by-step explanation:
A. It is an equation, but you can’t really do anything with it, let alone solve it.
C. 30+6 does not equal to 62, so definitely not.
D. 3x-4y is something, but there is no equa sign.
So, your andswer is B. 12=9+3x
Step-by-step explanation:
Triangle XYZ is isosceles.
Since Angle Y = 90°, Angle Z = (180° - 90°)/2 = 45°.
3x12=36
36+5=41
41-8=33
33/12=2 R9
2 9/12
Simplify
2 3/4
Midpoint coordinates= ((x1+x2)/2 , (y1+y2)/2)
=((0+-4)/2 , ( 4+-12)/2)
= (-2, -8)
