Answer:
w=2
Step-by-step explanation:
I'm too lazy to explain the first part but here:
3/4w=6/4
w=2
Answer:
Correct
Step-by-step explanation:
When you type 1/3 into a calculator it should give you something along the lines of .333333334. If you continue to round, eventually you will get 1.
1. Area of triangle
1/2(10)(12)=60
There are two triangles, so multiply by 2
=120
2. Find area of the rectangles
This is an isosceles triangle, so the two rectangles are congruent
(2)(13)(3)=78
3. Find area of bottom rectangle
10(3)= 30
4. Add everything up
120+ 78 + 30= 228
Therefore the surface area of this prism is 228
I hope i helped :)
The answer is a(n) = 6n - 2
