-4x+2z=14
-2x-4z=22
y=x+z+12
-4x-x+2z-2z=14+11
-5x=25
x=-5
10-4z=22
-4z=12
z=-3
y=-5-3+12
y=4
Answer:
x=-5; y=-3; y=4
44 that is probably the answer since it's half
Hello!
When adding matrices you add the numbers that are in the same position
1 + 4 = 5
0 + 1 = 1
3 + 7 = 10

We have two triangles with base 9ft and height 12.3ft and two triangles with base 11ft and height 11.9ft.
The formula of an area of a triangle:

Triangle #1:
b = 9ft and h = 12.3ft. Substitute:

Triangle #2:
b = 11ft and h = 11.9ft. Substitute:

The Lateral Area:

<h3>Answer: B. 241.6 ft².</h3>
