B hope this helped have a nice day! =D
Oh yes 4x5 is another answer so yep god I forgot that sorry!
Answer:
The perimeter is the distance all the way around the outside of a 2D shape. To calculate the perimeter, sum the lengths of all the sides.
Therefore, perimeter of the triangle = (2x - 8) + (2x + 5) + (30 - 3x)
Collect like terms: 2x + 2x - 3x - 8 + 5 + 30
Combine like terms: x + 27
Therefore, perimeter of triangle = x + 27
We are told that the perimeter is 25:
x + 27 = 25
Subtract 27 from both sides: x = -2
If x = -2, then the side with equation 2x - 8 = (2 x -2) - 8 = -12
A length cannot be negative, therefore the perimeter cannot equal 25.
The window that has the shape of a kite has the area of the glass as 648 centimetre squared.
<h3>What is area of a figure?</h3>
Area can be defined as the space occupied by a flat shape or the surface of an object. Therefore,
The window is the shape of a kite. Therefore, the square meters of the glass used for the window is the area of the window(kite).
Therefore,
area of kite = ab / 2
where
- a and b are the length of the diagonal
Therefore,
a = 18 + 18 = 36 cm
b = 15 + 21 = 36 cm
area of the window = 36 × 36 / 2 = 1296 / 2 = 648 cm²

Step-by-step explanation:
Looks like you want all equations converted into slope-intercept form.
- 2x + y = 2 ⇒ y = -2x + 2
- x + 2y = 4 ⇒ 2y = - x + 4 ⇒ y = - 1/2x + 2
- 2x - y = 2 ⇒ y = 2x - 2
- x - 2y = 4 ⇒ 2y = x - 4 ⇒ y = 1/2x - 2
