A prism and two nets are shown below:
Image of a right triangular prism and 2 nets. The triangle bases have base 4, height 3, and diagonal side 5. The length of the prism from the bases is 9.4. Net A has 3 rectangles in a row. The middle one has sides AC and CD. This middle one has triangle ABC on top and identical triangle below. Net B is the same except that the triangle base ABC is on top of the last rectangle which has sides AC and CD. Units are in inches.
Part A: Which is the correct net for the prism? Explain your answer. (2 points)
Part B: Write the measurements of Sides AB, BC, and CD of the correct net. (4 points)
Part C: What is the surface area of the prism? Show your work. (4 points)
Answer:
Pt A:I would say net A because if you fold net b it's going to be very tricky and hard to make and if you fold net A you get the exact shape.
Pt B:AB is 3in BC is 4 in and CD is 5 in.
Step-by-step explanation:
i hope this helps this helps you get out of trouble

Describe in your own words how the picture above shows 3(2 + x)
Answer:
6 + 3x
Step-by-step explanation:
3 * 2 and 3 *x
= 6 + 3x
you can not break that down any farther so it stays at "6 + 3x".
Hope this helps!
Answer:
3(2 + x) = 0
6 + 3x = 0
3x = -6
x = -6/3
x = -2

A penguin 10 feet in 5 seconds. At this speed: How long does it take the penguin to walk 52 feet?
Answer:
26 seconds
Step-by-step explanation:
If we want to find out how long it takes to walk 52 feet, we should start by figuruing out how long it takes to walk 50 feet.
10 x 5 is equal to 50
It takes 5 seconds to walk ten feet, and 5 x 5 = 25
Then, because 2 is 1/5 of 10, find 1/5 of 5, which is 1
Add 1 to 25 and you have your answer.
