Answer:
D) 394.68cm^2
Step-by-step explanation:
Area of a parallelogram is calculated by multiplying height to the base
13.8 × 28.6 = 394.68
Reflecting the polygon FGHI across the line involves flipping the line across the line y = -1
<h3>How to reflect the polygon?</h3>
The coordinates are given as:
F(2, – 1), G(5,2), H(8, 3), and I(6, 0)
The line of reflection is given as:
y = -1
To reflect the line, we apply the following rule of reflection
(x,y)
(x,-y-2)
So, we have the following coordinates of the image
F' = (2, – 1)
G' = (5,-4)
H' = (8, -5)
I' = (6, -2)

Answer: (2, -10)
Down and left are negative right and up are positive.
Answer: x=2/3
Step-by-step explanation:
Treat the 'more than or equal to' sign as a '=' then work it out like an ordinary algebraic equation.
2(4x-3) = -3(3x)+5x
8x-6 = -9x+5x
-6 = -9x+5x-8x
-6 = -12x
-6/-12 = x
1/2 = x
Then swap the '=' back for the other sign. This works for all of the '<' type signs
