<u>Step-by-step explanation:</u>
Here we have , an expression x2 + 4x + c or , 
. We need to find the value of c that makes the expression a perfect square binomial. Let's find out:
We have ,
⇒ 
⇒ 
Now , we know that 
Comparing above equation , to we get ;
⇒ { 
}
⇒ 
⇒ 
Therefore , the value of c that makes the expression a perfect square binomial is c=4 .

Answer:
10x - 3y = -109 .
Step-by-step explanation:
x^2 + y^2 = 109
Implicit Differentiation:
2x + 2y.y' = 0
y' = -2x/2y = -x/y
So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.
Equation of the tangent:
y - y1 = m(x - x1)
y - 3 = 10/3(x + 10)
y - 3 = 10/3 x + 100/3
3y - 9 = 10x + 100
-109 + 3y = 10x
10x - 3y = -109
