Answer:
D = 4, Z = 24
Step-by-step explanation:
6D+3Z = 96
5D+4Z = 116
multiply top by 5 and bottom by -6
top equation = 30D+15Z = 480
bottom equation = -30D-24Z = -696
Cancel 30D and -30 D
top equation = 15Z = 480
Bottom equation = -24Z = -696
15Z - 24 Z = 480 - 696
-9Z = 216
Z = 216/9
Z = 24
Now that we have the value of Z, we can substitute it in any equation to find D
6D + 3(24) = 96
6D + 72 = 96
6D = 96 - 72
6D = 24
D = 24/6
D = 4
The answer should be 9 rounded because 2 pi r 56.5 will give u that.
Yes, it has the same result
look at the picture. the red triangle is the first image. the green one is the result of reflecting over x-axis. then if you reflect it over y-axis, it would be the purple triangle
if you had rotated the red triangle at first, it would have the same result
good luck
