Convert to mixed number

Answer:
7) x= 5, 8) x= 6, 9) x= 7
Step-by-step explanation:
As per the secant theoram, if two secant intersect outside the circle then the product of the exterior secant and total length of each secant are equal.
7) ∴ 
opening parethesis and distributing 3 with x and 3.
⇒ 
subtracting 9 on both side.
⇒ 
cross multiplying
∴ x= 5.
8) 
Opening parethesis and distributing 4 with x and 4.
⇒ 
⇒ 
subtracting 16 on both side.
⇒ 
cross multiplying
∴ x= 6.
9) 
opening parethesis and distributing 5 with x and 5.
⇒ 
subtracting 25 on both side.
⇒ 
cross multiplying
∴ x= 7.
The answer would be C) 600 in2.
Distribute
18-8+15=13
combine like terms
10+15=13
25=13
