Answer:

330 000 m²

Step-by-step explanation:

1. Area of farm

$A = \text{1 km}^{2} \times\left (\dfrac{\text{1000 m}}{\text{1 km}} \right )^{2}= \text{1 000 000 m}^{2}$

2. Area for wheat

$A = \text{28 hm}^{2} \times \left (\dfrac{\text{100 m}}{\text{1 hm}}\right)^{2} = \text{280 000 m}^{2}$

3.Area for olive trees

$A = {\text{3900 dam}^{2} \times \left (\dfrac{\text{10 m}}{\text{1 dam}}\right )^{2}}= \text{390 000 m}^{2}$

4. Area for sunflowers

Total area = 1 000 000 m²

- Area for wheat = 280 000 m²

- Area for olive trees = 390 000

670 000

Area for sunflowers = 330 000 m²

Sunflowers occupy 330 000 m².

Answer:

x = $\frac{11}{7}$

Step-by-step explanation:

note that 64 = $2^{6}$ and 32 = $2^{5}$ , thus

$(2^{6}) ^{2x-1}$ = $(2^{5}) ^{x+1}$ , that is

$2^{6(2x-1)}$ = $2^{5(x+1)}$

$2^{12x-6}$ = $2^{5x+5}$

Since the bases on both sides are equal, then equate the exponents

12x - 6 = 5x + 5 ( subtract 5x from both sides )

7x - 6 = 5 ( add 6 to both sides )

7x = 11 ( divide both sides by 7 )

x = $\frac{11}{7}$
