The volume is very simple, is simply the product of the 3 dimensions, the length*width*height, so namely is 4*2*3.
now, how much material? well, that'd be the surface area, check the picture below. So the container is really just 6 rectangles stacked up to each other at the edges.
left and right, two 2x3 rectangles.
top and bottom, two 4x2 rectangles.
front and back, two 4x3 rectangles.
get the area of each, sum them up, and that's the surface area of the rectangular prism, and therefore that's how much material was used.
Simply the bottom to 2(x-3)
Then the top factors down into (x-3)(x+4)
The (x-3) term cancels out
You are left with ANSWER: (x+4)/2
thank you hope this helps

Step-by-step explanation:
please mark me as brainliest
First, separate the x's and the numbers:
+2x and -x
+3 and +5
Next, solve those sums:
+2x - x = 1x = x
+3 +5 = 8
Answer: A. x+ 8
Answer:
2, 3
Step-by-step explanation:
The graph of quantities in direct proportion.
Is a straight line passing through the origin, thus
the line always crosses the y- axis at |(0, 0 )
Thus the y- intercept is 0
