Answer:
<h2>12</h2>
Step-by-step explanation:
If the Quadrilateral A has side lengths 6, 9, 9, and 12 respectively and Quadrilateral B is a scaled copy of A with its shortest side of length 2, then to determine the scale used, we will find the ratio of the shortest side of quadrilateral A to that of quadrilateral B as shown;
ratio of shortest side
B:A = 2:6 = 1:3
This means that the quadrilateral B is 3 times smaller than A.
To find the perimeter of quadrilateral B, we will add all the side length of A and divide by 3 to get the perimeter of quadrilateral A by 3 as shown;
Perimeter of quadrilateral B = (Perimeter of quadrilateral A)/3
Perimeter of quadrilateral A = 6+9+9+12
Perimeter of quadrilateral A = 36
Perimeter of quadrilateral B = 36/3
Perimeter of quadrilateral B = 12
<em>Hence the perimeter of quadrilateral B is 12</em>

Answer:
The required expression for total number of points you earn is 
.
Step-by-step explanation:
Consider the provided information.
Let c represents the coin and p represents the points before getting star.
You earn 10 points for every coin you collect in a video game.
......(1)
You find a star that triples your score.
Now the total number of points you earn is(P):
Substitute the value of p from equation 1.

Answer:
-1/2
Step-by-step explanation:
We need to get a common denominator of 10
-4/5 *2/2 = -8/10
-8/10 +3/10
-5/10
Divide the top and bottom by 5
-1/2
