Use this formula:
a) d=11
Work:
d=sqrt((4-(-7))^2+(5-5)^2
d=sqrt((11)^2+(0)^2)
d=sqrt(121+0)
d=sqrt(121)
d=11
b) d=4
c) d = 16
d) d=160
e) d=12
The coordinates of X are (5, 11).
Solution:
Given points of the line segment are P(2, 2) and T(7, 17)
Let X be the point that partitions the directed line segment PT in the ratio 3 : 2
Using section formula, we can find the coordinate of the point that partitions the line segment.
Section formula:
Here, 
and m = 3, n =2
Substitute these in the section formula,
X(x, y) = (5, 11)
The coordinates of X are (5, 11).
Answer:
SA = 384 in ^2
Step-by-step explanation:
The surface area of a cube is given by
SA = 6 S ^2 where s is the side length
SA = 6 * (8) ^2
SA = 6 * 64
SA = 384 in ^2
Wher is the number line duh
Find greatest common factor because
ab+ac=a(b+c) and also therefor
ab+ac+ad=a(b+c+d)
so
6c^3d=2*3*c*c*c*d
12c^2d^2=2*2*3*c*c*d*d
3cd=3*c*d
common to all is 3*c*d or 3cd
3cd(2c²)+3cd(-4cd)+3cd(1)=
3cd(2c-4cd+1)
