Answer:
200%.
100% of 12 is 12 since for example if a coat is 10$ and 100% off then its now 0$. Therefore 200% is twice of 12 making it 24.
24=200% of 12

P= 2L + 2W
Answers
Add -2w to both sides of the equation
2L = p - 2w
Divide both sides by 2
2L = p - 2w
/2 /2
L = 1/2P - w

For a. the parent function is x^2, so 0.5x^2 should look about the same as x^2, so the answer is VI.
The graphs that match the function given are:
(a) VI, (b) III, (c) I, (d) II, (e) V, (f) IV
Consider the equations of the graphs given :
(a) y = 0.5 x²
This is a quadratic equation and thus will be a parabola.
This matches VI.
y is directly proportional to the square of x.
(b) y = 5/x²
Here negative values of y are not possible since x is squared.
Also, the values of y will be equal to a and -a.
This matches III.
y is inversely proportional to the square of x.
(c) y = x³
Here negative values of x will have the y values also negative.
Also, the value increases when x increases.
This matches I.
y is directly proportional to the cube of x.
(d) y = 1/x³
y value for x = -a is the negative of the y value for x = a.
Also, as x increases y decreases.
The function is not defined at 0.
This matches II.
y is inversely proportional to the cube of x.
(e) y = 3√x
Here since x is inside the cube, not defined for negative values of x.
As x increases, y also increases.
This matches V.
y is directly proportional to the square root of x.
(f) y = (0.5)ˣ
For negative values o x, the value of y will be high and for positive values of x, the value of y will be lower.
This matches IV.
y is exponentially related to x.
