The formula for finding the lateral area for a triangular prism is
So put in the values and you get
The formula for finding the surface area of a triangular prism is
SA = bh + (s1 + s2 + s3)H
So put in all the values and you get
SA = 9(8) + (9 + 8 + 12.04)23
SA = 740

Answer:
Mean: 169.4
Median: 171
Mode: 181
Step-by-step explanation:
I first sorted the numbers by value, least to greatest.
145 147 153 153 167 170 170 172 181 181 181 182 185 185
We can see that 181 occurs the most, 3 times, so it's the mode.
The median of this set will be the middle number(s).
When we take away 6 numbers from both sides we are left with 170 and 172, and the mean of these two numbers is 171. So the median is 171.
We can add all the numbers and divide by 14 to get the mean.
Hope this helped!

Answer:
Step-by-step explanation:
(Subtract 
from both sides of the equation to isolate

(Simplify)
(Symmetric Property of Equality)
(Divide both sides of the equation by 
to get rid of 's coefficient; remember that 
, so 
has a coefficient of )

Okay so a dilation means that you would multiply the area by your scale factor. 103 times 3 is 309. Your answer is 309
