In both cases,

(as a consequence of the interesecting secant-tangent theorem)
So we have
10.





(omit the negative solution because that would make at least one of AB or AD have negative length)
11.




(again, omit the solutions that would give a negative length for either AB or AD)
The slope between the points (x1,y1) and (x2,y2) is
slope=(y2-y1)/(x2-x1)
(0,6) and (5,-4)
x1=0
y1=6
x2=5
y2=-4
slope=(-4-6)/(5-0)=-10/5=-2
slope=-2

Answer:
24 cm^2
Step-by-step explanation:
The base of ∆Z is 4 cm, and its height is 12 cm. The area is given by the formula ...
A = 1/2bh
A = 1/2(4 cm)(12 cm) = 24 cm^2 . . . area of Z
The answer to your question is D
Answer:
Step-by-step explanation:
r=4*l
t=r-8
t=4l-8
r+t+l=100
4l+4l-8+l=100
9l-8=100
+8 +8
9l=108
