Answer:
D. no solution
Step-by-step explanation:
h-z=3(1)
h=3+z(minus z from both side)
put in the second equation
-3h,+3z=6(2)
-3(3+z)+3z=6
-9-3z+3z=6
-9=6( not true)
so the equation doesn't have a solution.
<span>(3-6i)-(4+2i)-(-7+i)
Answer is = 6-9i</span>
Answer: My answer would be 2
You would add up the length of all sides to get the area.
