What is 5(x-6)=2(x+3)

Mathematics
1 answer:
mezya [45]3 years ago
8 0

Answer:

x = 12

Step-by-step explanation:

Given

5(x - 6) = 2(x + 3) ← distribute parenthesis on both sides

5x - 30 = 2x + 6 ( subtract 2x from both sides )

3x - 30 = 6 ( add 30 to both sides )

3x = 36 ( divide both sides by 3 )

x = 12

Find the area of the shaded region. Round the the nearest tenth.
Brums [2.3K]

Answer:

226.084 sq.m.

Step-by-step explanation:

Radius of circle = 18.6 cm

Area of sector = \frac{\theta}{360^{\circ} }\pi r^2

Area of sector = \frac{123}{360} \times 3.14 \times (18.6)^2

Area of sector = 371.157 m^2

Area of triangle = \frac{1}{2} \times a \times b \times Sin x

a = OA = radius = 18.6 cm

b = OB = radius = 18.6 cm

x =123 °

Substitute the values in the formula

Area of triangle = \frac{1}{2} \times 18.6 \times 18.6 \times Sin 123

Area of triangle = 145.073 m^2

So, Area of shaded region = Area of sector - Area of triangle

                                            =371.157 m^2-145.073 m^2

                                            =226.084 m^2

Hence the area of the shaded region is 226.084 sq.m.
