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>

√-25
= √(25*-1) = √25 * √-1 = 5i, where i = √-1
The principal square root = 5i
Answer:
Step-by-step explanation: So there are 148 students total and we know the fifth graders filled up 12 rows and since each row has a number of 8 seats we should multiply 8 times 12, which is equal to 96. Now in order to find the number of rows needed for the fourth graders we should first, subtract 178 minus 96; that is equal to 82. Next, we should divide 82 by the number of seats in each row since what we are trying to find id the number of rows needed for the fourth graders. So, we should divide 82 by 8 which is equal to 10. 25.
The number of rows needed is 11 since all students need to have a seat; the answer cannot be 10 because that means a few students would not have a seat.
