The surface area increases by a factor of 4. 2^2= 4.
The area of the long side is 3×1= 3cm^2 on the small prism.
The area of the long side is 6×2= 12cm^2 on the large prism.
12/3= 4.

Step-by-step explanation: I just did the question
Answer:
1 A the first store.
2. B The second store.
Step-by-step explanation:
1. The store with the dearest towel is The First one ( $20 compared with $18).
2. The equation for the cost in the first store is P = 20n + 25.
The cost in the second store is given by P = 18n + 35.
For 15 towels first store charges:
20 * 15 + 25 = $325.
Second store charges:
18 * 15 + 35 = $305.
A parabola is a mirror-symmetrical planar curve that is nearly U-shaped. The vertex of the parabola will lie at (-3,2).
<h3>What is the Equation of a parabola?</h3>
A parabola is a mirror-symmetrical planar curve that is nearly U-shaped.
y = a(x-h)² + k
where,
(h, k) are the coordinates of the vertex of the parabola in the form (x, y);
a defines how narrower is the parabola, and the "-" or "+" that the parabola will open up or down.
Comparing the given equation with the equation of a parabola, we will get,
y = a(x -h)² + k
y = -4(x+3)² + 2
Hence, the vertex of the parabola will lie at (-3,2).
