The width of a rectangle is the length minus 2 units. the area of the rectangle is 35 units

Step-by-step explanation:

Width=(Length-2) units

W=(L-2) units

Area of the rectangle= 35 square units

Area = length* Width

Subtracting 35 both sides:

Solving the quadratic equation for 'L' ;

Using factorization:

Taking common from the equation :

OR

The length cannot be negative, therefore Length(L)= 7

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
