Answer:
Step-by-step explanation:
Note that in this diagram, point A represents point X, point B represents point Y, and point C represents point Z.
From the diagram, it appears as if 
. To determine if this is the case, we can find the slopes of both segments.
Since these slopes are negative reciprocals, we know that they are perpendicular.
This means we can use the formula 
, where b is the base (XY) and h is the height (XZ).
- Note these are interchangeable.
Using the distance formula,
This means the area is 
Answer:
7 inches
Step-by-step explanation:
I cant see the illustration, but I will assume it is a rectangle. The formula for the perimeter of a rectangle is P=2w+2l
let P represent the perimeter of the window in inches
let w represent the width of the window in inches
let l represent the length of the widow in inches
(L is l whereas one is 1)
So we know w=5 and P=24
This lets us have the equation 24= 2 x 5 + 2l
24=10 + 2l
14=2l
7=l
Answer:
10(3.14) = 31.4
20(3.14)=62.8
It will be twice the size
Answer is A. Can rule out b and c. Also d isn't proportional
