Answer:

Step-by-step explanation:
we know that
The <u>distance formula</u> is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse. The hypotenuse of the triangle is the distance between the two points
The formula to calculate the distance between two points is equal to

we have
A(1, 1) and B(7, −7)
Let
(x1,y1)=A(1, 1)
(x2,y2)=B(7, −7)
substitute the given values in the formula





Answer:
x= -2
Step-by-step explanation: If you feel skeptical about my answer, then you should plug -2 back into the equation to check if it's correct. And it's correct for me when I did it.

Answer:
d=65
Step-by-step explanation:
Length: 56
Width: 33
Answer:
The coordinates of the end point B are (14 , 8)
Step-by-step explanation:
let B(x , y)
M midpoint of A and B
⇔ 8=(x+2)/2 and 11=(y+14)/2
⇔ 16=x+2 and 22=y+14
⇔ x=14 and y=8
