4 |x+9| < 40
|x+9| < 40/4
|x+9| < 10
x + 9 < 10. x < 1. (Positive answer: <)
x + 9 > - 10. x > - 19 (negative answer: >)
Answer:
20
Step-by-step explanation:
Since chord AB and DE are at equal length from the centre, they are equal in length.
AB = DE
3x-7 = 5(x-5)
3x-7 = 5x-25
-7+25 = 5x -3x
18 = 2x
Dividing both side by 2
x = 9
Now
AB = 3(9)-7
= 27 -7
= 20
