Answer:
Consider this rectangle. The perimeter is P = 2(3) + 2(6) = 18 cm. A rectangle with length 6 centimeters and width 3 centimeters. Suppose the dimensions of the rectangle are all multiplied by 4. The new rectangle would have the dimensions . The perimeter of the new rectangle would be cm. The new perimeter will be times as large as the perimeter of the original rectangle.

<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:
The solutions are:
In which:
Item a:
The coefficients are a = 2, b = -3, c = -4, hence:
Item b:
The coefficients are a = 1, b = 2, c = 2, hence:

The answer is D because my dad said so and my dad knows everything
X = -b/2a
x = -8/4
x = -2
Plug -2 in for x and solve for y
y = 2(-2)^2 + 8(-2) -3
y = 8 -16 -3
y = -11
Vertex (-2, -11)
