If the square has sides of 6 the circle has a radius of 3 so it's area is 9pi
Use slope formula: y2-y1/x2-x1
XZ: -5/9
YZ: 2/7
XY: -7/2
XYZ is a right triangle because two of these slopes have a product of -1.
(YZ and XY does). We are all busy these days.

= (3a)² - 2*3a*4 + 4²
= 9a² - 24a + 16
Answer:
-5 degrees per hour
Step-by-step explanation:
In 10 hours, the temperature dropped -50 degrees (38 + 12, and make it negative because the temperature went down, not up).
So divide -50 by 10
-50/10 = -5
