What is the IQR?

9

Step-by-step explanation:

List the numbers in order

You'll see the Q3=25 and Q1=16

since IQR is Q3-Q1, you do 25-16 to get 9

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
