Answer:
Step-by-step explanation:
n - 4 < 5
n < 9
So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.
0
Length = Width+6
Area = W * L
Area = W * (W+6)
Multiply it out
Area = W^2 + 6W
Area=72
72 = W^2 + 6W
subtract 72 from both sides
0 = W^2 + 6W - 72
12 * 6 = 72
12 - 6 = 6
Factor it
0 = (W-6)(W+12)
W = 6 and W = -12
Width must be 6 cm because Width can't be negative
L = W+6
L = 6 + 6
L = 12 cm
