Answer:
Centre: (6,0)
Radius: 2
Step-by-step explanation:
r² = 4
r = 2
x = 21/10
3/10 = x/7
Cross multiply.
10x = 21
Hello,
<u>k=-3 and h=-2</u>
h+1 is thus a root of x²+(-3-1)*x-5=0
x²-4x-5=0
x²+x-5x-5=0
x(x+1)-5(x+1)=0
(x+1)(x-5)=0
h+1=-1
<u>h=-2</u>
6x + 2
Explanation:
4 + -2 = 2 and x + 3x + 2x = 6x
