Elimination
2 ( 2x -y=5) multiply = 4x -2y=10
3x +2y=4
* add the X's and the 10 and 4 7x=14 * divide by 7 giving you
x=2
*and then plug back in
3(2) +2y =4
6 + 2y = 4
2y= -2
y= -1
the order pair is ( 2 , -1)

Answer:
= 32√3 ft²
Step-by-step explanation:
Area of the trapezoid will be equal to the area of the square and that of the triangle.
Considering the triangle part;
Cos 60 = x/8
x = 8 × sin 60
= 4
Base of the triangle part = 4 ft
Therefore, top of the trapezoid = 6 ft
Height = 8 × sin 60
= 8 × √3/2
= 4 √3
Area of the trapezoid
Area = ((a+b)/2) × h
= ((6 + 10 )/2 )× 4√3
= 16/2 × 4√3
= 32√3 ft²
