Answer:

44

Step-by-step explanation:

k=1: 2*1-4 = -2

k=2: 2*2²-4 = 4

k=3: 2*3²-4 = 14

k=4: 2*4²-4 = 28

-2 + 4 + 14 + 28 = 44

Answer:

126 inches

Step-by-step explanation:

If your drawing is on a 1 : 40 scale, to find the scale's height, divide the ride's height by 40.

420 / 40 = 10.5

So the drawing will be 10.5 feet tall.

To convert 10.5 feet to inches, multiply it by 12.

10.5 * 12 = 126 inches
