Proofs can be tricky! What helps me is thinking through them step by step and how I would prove I did something. While I'm not entirely sure what options you have for this proof, I've given my best guess.
Hope this helps!! :)
Answer:
1. D
2. A
3. H
4. C
5. G
Step-by-step explanation:
Ok, so let's do this step by step, you'll only need to picture each panel/side individually, not the whole prism at once.
Start at point A, on both the prism and the flat layout.
On the layout, start with point A. You see that the #1 is along the long edge of A, on the same side... if you transpose that to the prism, you will arrive to vertex D. Do you see it?
Then from point 1 (D), we travel again on the long segment... to reach point #2, which is again point A.
For number 3, we see it's across the rectangle shape from F... if we look at that situation on the prism, we arrive at point H.
Point #4 is across point 1 (D) and diagonal to point 2 (A), so it's point C.
Point #5 is at the crossing of points C and F... so it's G based on the prism.
The solution of the inequality 3x - 8 <= 23 or -4x + 26 >= 6 is x <= 31/3
<h3>How to solve for x?</h3>
The inequality is given as:
3x - 8 <= 23 or -4x + 26 >= 6
Evaluate the like terms
3x <= 31 or -4x>= -20
Make x the subjects
x <= 31/3 or x <= 5
x <= 31/3 has a wider domain that x <= 5
Hence, the solution of the inequality 3x - 8 <= 23 or -4x + 26 >= 6 is x <= 31/3

Answer:
x=-1, 3
2 solutions, strategies=quadratic formula
Step-by-step explanation:
1. square the whole equation
(√2x+3)²=(x)²
2x+3=x²
since it becomes a quadratic equation, take all terms on one side = to 0
x²-2x-3=0
Use the quadratic formula, because the equation cannot be factored.
x=(-b±√b²-4ac)/2a
x=(-(-2)±√4-4×1×-3)/2×1
x=(2±√4+12)/2
x=(2±√16)/2
x=(2±4)/2
x=1±2
x=1+2, 1-2
∴x=-1, 3
