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.
First, find the area of the circle A=pi r^2 = 3.14 (8)^2=200.96
the radius is half the diameter so r=16/2=8
Second, find the area of the triangle A=(hb)/2=(8*16)/2=64
since the triangle is resting on the diameter of the circle that means the height of the triangle is also the radius of the circle so h=8 and b=16
Third, subtract the area of the triangle from the area of the circle to find the area of the shaded regions.
so...
200.96-64=136.96
is the answer.
Answer:
x^2 +14x+49
Step-by-step explanation:
Area = length * width
= ( x+7) * ( x+7)
FOIL
first: x^2
outer: 7x
inner: 7x
last: 7*7 = 49
Add them together
x^2 +7x+7x + 49
Combine like terms
x^2 +14x+49
