Answer:

(2,1,0)

Step-by-step explanation:

3x+3y+6z=9

3(2)+3(1)+6(0)=9

6+3+0=9

6+3=9

9=9

x+3y+2z=5

x(2)+3(1)+2(0)=5

2+3+0=5

2+3=5

5=5

3x+12y+12z=18

3(2)+12(1)+12(0)=18

6+12+0=18

6+12=18

18=18

If the radius is 18 cm and the angle at centre of circle is 120° then the

PolarNik [594]

The area of a sector is 339.336 cm²

The area of a sector is defined to be as the region of space bounded by a boundary from the center of the circle.

It can be determined by using the formula:

$\mathbf{A = \dfrac{\theta }{360}\times \pi r^2 }$

Given that;

Radius r = 18 cm
Angle θ = 120°

Then. the area of the sector can be calculated as:

$\mathbf{A = \dfrac{120}{360}\times \pi (18)^2 }$

$\mathbf{A = \dfrac{1}{3}\times 3.142 \times 324 }$

A = 339.336 cm²

1. 7 + -10 = -3.
2. -3 + -8 = -11
3. 4 + -5 = -1
4. 2 + -6 = -4
(You basically need to add negative numbers to positive numbers in order to get negative numbers.)
