Answer:
15cm
Step-by-step explanation:
the width is xcm
22 + 22 + 2x = 74
44 + 2x = 74
2x = 30
x = 15
the width is 15cm
I believe the answer is
A is $45 billion
B is $60 billion
Move k to the other side to isolate d.
So we will get 3d = 8c - 8d - k
Now divide both sides by 3 to isolate d.
So d = 8/3c - 8/3d - k/3
