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.
Answer:
Step-by-step explanation:
y-intercept is the y-value when x = 0
y - 3 = -2(0 + 5)
y - 3 = -2(5)
y = -7
Do 9x2.5x10 = 225in3 the 3 at the end is a exponent so put it at the top after 225
