Answer:
x = -4 and x = -14
Step-by-step explanation:
Our equation is (x + 9)² = 25
Applying the square root property we would need to take the square root of both sides: 
This give us x + 9 = ±5
Here we have two equations since taking the square root gives us a positive and negative value
Our first equation is x + 9 = 5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -4
Our second equation is x + 9 = -5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -14
Step-by-step explanation:
a.
Female fall= 42 (19+37+18=74, 116-74)
Female total= 116 (229-113)
Male spring= 21 (50+16+26, 113-92)
Total fall=58 (40+87+44,229-171)
b.
Fall
