(x-3)^2 + (x+5)^2=9^2
(x^2-6x+9) + (x^2+10x+25)=81
2x^2+4x+34=81
2x^2+4x-47=0
From here just use quadratic formula

- <u>25.12 cm</u>
Answer:
The answer to your question is 7 times
Step-by-step explanation:
Data
Percent of accuracy = 35%
Times she is at bat = 20
Times she hit the ball = ?
Process
1.- Use proportions to solve this problem
20 times will be the 100% because is the total number of times she is at bat.
20 times ------------------ 100%
x ------------------ 35%
x = (35 x 20) / 100
x = 700 / 100
x = 7
2.- Conclusion
From 20 times she is at bat, she will hit the ball 7 times.
