Confusing question but I would get 0, as if you have 4cm, that squared = 16cm^2. Therefore if it were increasing anymore, then you would not be able to get a value of 16.
Answer:
r = -9/10
Step-by-step explanation:
Given
7/10 = r - (-8/5)
Required
Solve for x
7/10 = r - (-8/5)
We start by opening the bracket
7/10 = r + (- -8/5)
7/10 = r + (8/5)
7/10 = r + 8/5
Subtract 8/5 from both sides
7/10 - 8/5 = r + 8/5 - 8/5
7/10 - 8/5 = r
Solve the fraction by taking their LCM
(7 - 16)/10 = r
-9/10 = r
Reorder the above
r = -9/10
Hence, the value of r is -9/10

Answer: 8 1/3 yards per second
500 yards/60 seconds=8 1/3 yards per second
Check Work:
8 1/3 yards per second*60 seconds=500 yards per minute.
Hope this helps!
2n + n/2 = 10
4n/2 +n/2 =10
5n/2 = 10
5n = 20
n = 4
