Answer:
The length of each side is 31.5m, 26.5m, 7m
Step-by-step explanation:
Let the length of the first side of the triangle be x meters.
Then, the second side is x-5 meters.
The third side is given as 7 meters.
The perimeter is 65 meters
This gives us the equation:
The length of each side is 31.5m, 26.5m, 7m
Answer:
Choise B:
Step-by-step explanation:
For this exercise you must remember the multiplication of signs:
By definition, equivalent expression have the same value.
Then, you can find an equivalent expression to the expression provided in the exercise by simplifying it.
So, given:
To simplify it, you can distribute the negative that is located outside of the parentheses (in order to eliminate the parentheses).
Applying this procedure, you get the following equivalent expression:
Therefore, as you can notice, the expression obtained matches with the one shown in Choice B.
