Answer:
304m^2
Step-by-step explanation:
First find the surface area of the base by multiplying the length by the width.
(12m) (8m)= 96m^2
Second, find the surface area of the front and back triangles using the formula <em>1/2 (base) (height)</em>. Use the length for the base.
1/2 (12m) (10m)= 60m^2
Next, find the surface area of the side triangles using the formula <em>1/2 (base) (height). </em>Use the width as the base.
1/2 (8m) (11m)= 44m^2
Last, add the surface area of each section. Make sure you add the area of each face.(we only solved for 1 of the front/ back triangles and 1 of the side triangles) To make it easier to understand I wrote out an equation to show how I added the surface areas.
base=a, front/ back triangles= b, side triangles=c
SA= a + 2b +2c or SA= a +b +b +c +c
Using one of the equations above solve for the total surface area.
SA= (96m^2) + (60m^2) +(60m^2) +(44m^2) +(44m^2)
or
SA= (96m^2) + 2(60m^2) +2(44m^2)
SA= (96m^2) +(120m^2) +(88m^2)
SA= 304m^2
(make them equal to each other)
10x-1 = 14x-37
(combine like terms)
-4x = -36
(divide by -4)
x=9
Hope this helps! Have a good day/night!
The 3 terms are 1, -1, and -3.

Answer:
<em>The answer is 24</em>
Step-by-step explanation:
The given triomino follows as sequence that,
<em>The upper no. × The right no. -The left no. = The middle no </em>
As we can see this by analyzing the three triominoes
first triominoes
4 × 2 - 4 =4
second triominoes
6×1 - 5 = 1
third triominoes
3×4 -0 = 12
∵ Finding fourth triominoes
9×3 - 3 = 24
<em> </em><em> ∴ The answer is 24</em>
