Answer: Is your question "What is the length of each side?"
Let x = the length of the second side
Let x - 5 = the length of the first side
Let (x - 5) - 2 = the length of the third side
P = a + b + c
x + x - 5 + x - 7 = 42
3x - 12 = 42
3x = 54
x = 18 yards
x - 5 = 13 yards
x - 7 = 11 yards
Step-by-step explanation:
2x+3+132=180
2x+135=180
subtract 135 from both sides
2x=45
divide both sides by 2
x=22.5
Answer:
Semiconductors are somewhere in-between conductors and insulators. This means that they are specific when it comes to conducting electricity meaning that their conduction of electricity varies based on their condition at the time.
For instance, they can conduct electricity when heated.
Properties:
1. Perfect insulator at Absolute Zero.
As mentioned above, semi conductors are better at conducting electricity when they are heated. At Absolute zero - the lowest temperature possible - therefore, these materials would conduct absolutely no electricity thereby making them perfect insulators.
2. More resistance than Conductors but less than Insulators
As mentioned above, they have properties in-between those of insulators and conductors. One of those is their resistance. They can resist more than conductors but less than insulators.
The answer is 6
First, you must put the values in the formula.
Then, you must simplify the exponents.
Next, subtract 64 on both sides.
Finally, eliminate exponents.
