Answer:
The answer is - 2 < x < 2
Step-by-step explanation:
–5 < 2x – 1 < 3
Add 1 to both sides to eliminate - 1
That's
- 5 + 1 < 2x - 1 + 1 < 3+ 1
- 4 < 2x < 4
Divide both sides by 2
That's
- 4/2 < 2x/2 < 4/2
The final answer is
<h3 /><h3>- 2 < x < 2</h3>

Answer: Any isosceles triangle is a counter example. More specifically, a triangle with sides 7, 7 and 3
When forming your triangle, make sure you apply the triangle inequality theorem. This is the idea where adding any two sides leads to a result larger than the third side. So we have
7+7 = 14 which is larger than 3
7+3 = 10 which is larger than 7
By definition, an isosceles triangle has two congruent sides. Some books say "at least 2 congruent sides", but I'll go with the first definition. If you want all three sides to be congruent, then you'd go for the term "equilateral".

Step-by-step explanation:
3 times 17 to find the number of feet =51
51 time $34 (the price per foot ) to find total
Because 4x2 = 8, so 4x7=28, then you times 28 by 2 which equals 56 and 8x7=56
