Answer:
Choice B and Choise C.
Step-by-step explanation:
Equivalent expressions are those expressions that have the same value but they look different.
Given the following expression provided in the exercise:
You need to remember the multiplication of signs in order to find the equivalent expressions:
Then:
- Eliminating the parentheses, you get this equivalent expression:
- Since the mulplication of two negative signs gives yous a positive sign, you can rewrite the original expression in this form:
This is an equivalent expression to
Answer:

Answer:
n= 2
Step-by-step explanation:
i know this is right
In the problem, two legs measurement were given such as:
Leg 1 = 12 inches
Leg 2 = 15 inches
We need to solve for the third leg. Since it is a right triangle, we can use Pythagorean theorem in solving the missing leg:
c²=b²+a²
When we assume that the third leg is the "c", we can for the value such as:
c² = 12²+15²
c=19.21
When we assume that the third is either "a" or "b":
15² =a² + 12²
a=9
Then, the possible measurement of the third leg is 9 or 19.21.
The difference between the two possible answer is shown below:
Difference = 19.21 -9 = 10.21
Difference =10.21
