5384=5000+384
4 * 5384 = 4(5000+384) = 4 * 5000 + 4 * 384
4 * 5000 = 20000
20000 + 4 * 384
So to find 5384 * 4, you add 20000 to 4*384. Less calculations
The answer is B, 4/-9 = 2/-3

Answer:
<em>AC</em> = 18.9; m∠A = 66.9°
Step-by-step explanation:
- 2021 Edmentum
L = 2W
P = 2L + 2W
60 = 2(2W) +2W
60 = 4w +2w
60 = 6w
60/6 = 6w/6
w = 10
L= 2(10)
L = 20
Check
P = 2L + 2W
60 = 2(20) +2(10)
60 = 40 +20
60 = 60
