D I’m pretty sure AC is correct
You take the top box and combine it with the bottom right hand box and remove the right stick on the bottom box to continue combination.
Answer:
1/2 hr 27.5
1 1/2 hr 82.5
last one is 2 hr and 110
Step-by-step explanation:
-20 * 3 / -30 / 3
First multiply the top and divide the bottom to simplify the problem:
-20 * 3 = -60
-30/3 = -10
Now you have -60 / -10
Divide:
-60 / -10 = 6
Let, the width = x
length = 2x - 4
Perimeter = 2(l+w)
Substitute their values,
72 = 2(x+2x-4)
72 = 2(3x-4)
6x - 8 = 72
6x = 80
x = 80/6
x = 13.3
In short, Your Answer would be 13.33 cm
Hope this helps!
