Answer:factor of 9
Step-by-step explanation:
Given
prism were changed by a scale factor of 3
Suppose prism is rectangular in shape
So surface are is 
Where l=length
w=width
b=breadth
So new length,breadth and width is
So new surface area would change by a factor of 9
6,4 is the correct answer
To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360°.
Answer:
536.6
Step-by-step explanation:
First I found the area for the rectangles which is (15x10) multiplied by 3.
Then I found the area for the triangles which is A=(1/2)(8.66)(10). Which equals 43.3, then multiplied that by 2.
Add all the areas together (150)(3)+(43.3)(2)=536.6
The reason this is false is because the number you are subtracting with can be greater than the number your are subtracting from, resulting in a negative number. Or, if the order doesn't matter, the numbers can be the same. This results in a difference of 0, neither positive nor negative.
