1. 4i x -10i = -40ii

ii = i^2 = -1

-40*-1 = 40

2. -6-9 = -15

5i- - 5i = 5i + 5i = 10i

answer = -15 +10i

3. raise both sides to the 3rd, and solve for x. x = -12

4. the equation would be x^2+36 =0

Answer:

424 cm²

Step-by-step explanation:

The figure is composed of a square and a trapezium on top

A of square = 18² = 324 cm²

A of trapezium = $\frac{1}{2}$ h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 8, b₁ = 18 and b₂ = 7 , then

A = 0.5 × 8 × (18 + 7) = 4 × 25 = 100 cm²

Area of hexagonal park = 324 + 100 = 424 cm²
