Answer:
y = -1/4x^2 -3/2x +3/4
Step-by-step explanation:
You know that vertex form is ...
y = (1/(4p))(x -h)^2 +k
for a focus-vertex distance of p and a vertex of (h, k).
Here, the focus-vertex distance is 2-3 = -1 (difference of y-coordinates), and the vertex is (h, k) = (-3, 3). This means the vertex form equation is ...
y = -1/4(x +3)^2 +3
Expanding the square gives ...
y = -1/4(x^2 +6x +9) +3
y = -1/4x^2 -3/2x +3/4

Answer:
D. (3x² + 10w + 8) square inches
Step-by-step explanation:
the new width of the rectangle: w + 2
the new length of the rectangle: 3w + 4
the area: (w + 2)(3w + 4) = 3w² + 10w + 8
