Answer:
Step-by-step explanation:
The range is 10
If you work out the constants it says:
25+x²=100
Which simplifies to x=√75 or x=-√75
Not sure about the summer part, but the answer should be 1 / 6. Maybe your question is wrong.
Answer:

Step-by-step explanation:
To find the distance between a point (m, n ) and the line
Ax + By + C = 0
d = 
Here (m, n) = (6, 2) and rearranging the line
6x - y + 3 = 0 ← in general form
with A = 6, B = - 1 and C = 3 , then
d = 
= 
=
Rationalise the denominator by multiplying numerator/ denominator by 
=
×
=
← cancel 37 on numerator/ denominator
=
