Answer:
3) 2.7
Step-by-step explanation:
The distance between two points 
and 
can be determined by:
Since the points are X(1, 2) and Y(6, 7). The distance between the two points is
the x value for the point located 1/3 the distance from X to Y,
The x value = 
Answer:
The solution to this question is 39
Step-by-step explanation:
Given that :
√(3x+7)+2√(x-8)=0.
√(3x+7)=-2√(x-8) (i)
square of the equation (i)
Then
(√(3x+7))^2=(-2√(x-8))^2
we know that √a*√a=(√a)^2=a So,
(3x+7)=4(x-8)
3x+7=4x-32 //multiply by 4
32+7=4x-3x exchange the value.
39=1x
x=39.
