To find surface area, you can find the area od all sides and add them together
First, area of an triangle is 1/2 length times width
So you do 1/2 6*9= 1/2 54= 27 The area of the three triangles are 27
27 times 3 is 81
81 plus the base of 15.6 is 96.6
The surface area is 96.6 meters squared
Answer:
Step-by-step explanation:
Initial value is $400
Value after 9 years is zero
Change in value over 9 years is $400
<u>Rate of change is:</u>
Answer: 12
Step-by-step explanation:
12 times 12 is 144 so 12.in each row
Answer:
A. The lines stay parallel
Step-by-step explanation:
Rigid transformations do not change angle or line relationships. When the parallel lines are rotated they stay parallel. Reflecting them will keep them parallel. If this were not true, then figured with parallel lines like rectangles and squares would change shape when reflected.
