Hi there!
Since ST is a tangent to the circle, we can use the relationship: tangent squared = external secant segment x entire secant segment.
WORK:
(I will be using x in place of ST)
x^2 = 7(23 + 7)
x^2 = 7(30)
x^2 = 210
x = squareroot(210) or approximately 14.5 inches
Hope this helps!! :)

14 + 5x + 15 - 7x
29 - 2x</span>
Step-by-step explanation:
3/2(4x-1)-3x = 5/4-(x+2)
6x -3/2 -3x = 5/4 -x -2
3x -3/2 = 5/4-2-x
4x=5/4 -2 +3/2
4x= (5-8+6)/4
4x=3/4
x=3/16
Answer: r= 25/3
Step-by-step explanation:
r-4(r+6)=-49 distribute the 4
r-4r-24=-49 combine like terms
-3r-24=-49 add 24 to both sides
-3r=-25 divide by -3
r= 25/3 answer
Substitute the x and y values from (3,2).
Formula: y=mx+b
2= 3(3)+b
2-9= -7
y=3x-7
