Answer:
A.
Step-by-step explanation:
The coordinates of the point P which divides the line segment AB made by the points A(-7,2) and B(9,-6) is (x,y) = (5,-4)
<h3>What is the coordinate of the point which divides a line segment in a specified ratio?</h3>
Suppose that there is a line segment
such that a point P(x,y) lying on that line segment
divides the line segment
in m:n, then, the coordinates of the point P is given by:

where we have:
- the coordinate of A is

- and the coordinate of B is

We're given that:
- Coordinate of A is
= (-7,2) - Coordinate of B is
= (9.-6) - The point P lies on AB such that AP:BP=3:1 (so m = 3, and n = 1)
Let the coordinate of P be (x,y), then we get the values of x and y as:

Thus, the coordinates of the point P which divides the line segment AB made by the points A(-7,2) and B(9,-6) is (x,y) = (5,-4)

Answer:
Surface area: 18,144m
Volume: 139,968m³
Step-by-step explanation:
Surface area:
72x72 = 5184m on bottom, as well as top
5184+5184= 10368
27x72 for side length = 1944
1944 x 4 sides = 7776
7776+10368 = 18,144m surface area
Volume:
72x72x27 = 139,968m³
Answer:
ans:- 14
Step-by-step explanation:
let length = x
so, width= 2x -1
perimeter= 2(l +b)
82 = 2(x+ 2x-1)
41 = 3x - 1
3x = 42
x = 14
