Answer:
The average is 103.8125
Step-by-step explanation:
Subtract 4277 by 2616 to get the difference, then divide by the year gap (16) and you get your average!
4277 - 2616 = 1661 ÷ 16 = 103.8125
Volume of the box = length * width * height
length of original peice = x + 10 , width = x
length of box (x + 10) - 4 = x + 6
width of box = x - 4
height of box = 2
so we have
2 * (x -4) * ( x + 6) = 832
2x^2 + 4x - 48 = 832
2x^2 + 4x - 880 = 0
x^2 + 2x - 440 = 0
(x + 22)(x - 20) = 0
x = 20
so width of original piece of metal = 20 ins , length = 30 inches.
