Answer:
x = [-1 | 5, 2 | 1]
Step-by-step explanation:
We assume your notation is used to describe 2×2 matrices.
Solve for x:
2x -k = m
2x = m + k . . . . add k
x = (1/2)(m +k) . . . . multiply by 1/2
Fill in the values:
x = 1/2[2+(-4) | 8 +2, -2+6 | 5+(-3)]
x = [-1 | 5, 2 | 1]

<u>To find the area of a complex shape</u>:
⇒ must split into simpler shapes
- a rectangle of <u>8m by 7m</u>
- a rectangle of <u>2m by 8 m</u>
<u>Now let's find</u>:
- Area of a rectangle of <u>8m by 7m</u>
- Area of a rectangle of <u>2m by 8m</u>
<u>Total Area</u> = 56 + 16 = <u>72 m²</u>
<u>Answer: 72 m²</u>
