10×8 is that what you mean
Answer:
the answer is no.
Step-by-step explanation:
the x-value 2 keeps repeating which makes this not a function.
Given:
Area of a sector = 64 m²
The central angle is 
.
To find:
The radius or the value of r.
Solution:
Area of a sector is:
Where, r is the radius of the circle and 
is the central angle of the sector in radian.
Putting 
, we get
Taking square root on both sides, we get
Therefore, the value of r is 
m.
Answer:
x=−1 or x=−6
Step-by-step explanation:
Multiply all terms by x and cancel:
xx+6=−7x
x2+6=−7x(Simplify both sides of the equation)
x2+6−−7x=−7x−−7x(Subtract -7x from both sides)
x2+7x+6=0
(x+1)(x+6)=0(Factor left side of equation)
x+1=0 or x+6=0(Set factors equal to 0)
x=−1 or x=−6
Check answers. (Plug them in to make sure they work.)
x=−1(Works in original equation)
x=−6(Works in original equation)
