Answer:

Step-by-step explanation:
We see that diagonal AB is also the hypotenuse of a triangle where the other 2 side lengths are 4 and sqrt{45}. Using the Pythagorean theorem, we get that diagonal AB is 
Answer:
Perimeter: 44
Area: 96
Step-by-step explanation:
Perimeter - Just add all the sides together, 4 + 10 + 12 +7 + 8 + 3.
(The 8 and the 3 are apart of the sides that are not labeled. Since 12 - 4 = 8, and 10 - 7 = 3, That's where these numbers come from.)
Area - 4 * 10 = 40,
+ 8 * 7 = 56,
--------------------------------
= 96

Answer:
28.26
Step-by-step explanation:
Area of a circle is pi * radius squared
The diameter is 6, so the radius is 3
pi * 3^2 = 3.14 * 9 = 28.26
The slope is the same as rate of change. In a linear graph, it is the change in y over the change in x.
One cost for the first price is $0.16and the second on is 0.14 so the second one is the better deal
