Answer:
We can't find the answer unless there's the total amount of circumstances.
Step-by-step explanation:
QR= 2x-7
RS= x-61
QS= x+11
2x+7+x-61+x+11
? = 4x-43
9514 1404 393
61.4
The length of two semicircles of diameter 10 is the circumference of a circle of that diameter:
C = πd = 10π ≈ 31.4
The perimeter includes that length plus the lengths of two straight sides that are 15 units each.
P = 31.4 + 2×15
P = 61.4 . . . . units

I only know these two answers and I'm not sure if it's right
There is a loss of 2 yards.
To find the overall gain or loss, we add or subtract there values.
Initially, we have 0 yards.
Records 14, so 0 + 14 = 14, that is, for now a gain of 14
Then loses 7, so 14 - 7 = 7, for now a gain of 7.
Then, 7 - 9 = - 2, so in all, there is a loss of 2 yards.
