Step-by-step explanation:
Given
Shape: Equilateral triangle

Required
Draw the triangle
First, we determine the side lengths.
The perimeter of an equilateral triangle is:

So, we have:

Answer: The first one, the last one,
Step-by-step explanation:
1. Since it's m - 7 you would have 7 to both sides so you would in fact have m < 13. If you double check your answer, you see that if m is say 12 (because 12 is obviously less than 13), 12 - 7 < 6
2. Again, use the same process on this problem as the first one. Add 8 to each sides because it's you're subtracting 8 from n. So you end up with n > 13. Check your answer. Say n is 14. 14 - 8 > 5
3. This one is different because you are adding 5 to p. So in order to get p by itself, you need to subtract 5 from both sides. p < 5. Say p is 4, 4 + 5 < 10.
When working with problems like these, you need to isolate the variable on one side and get it by itself.
Answer:
the answer to the problem is h=7
