Answer:
√41, or about 6.4 units
Step-by-step explanation:

√41 is about 6.4 units
Answer:
No
Step-by-step explanation:
No, 5cm, 5cm, and 15cm cannot create a triangle because the side lengths do not follow the formula a + b > c. Since 5 + 5 = 10, and 10 is not greater than 15, these side lengths won't be able to form a triangle.
Hope this helps!!
Number 4 is 1
3-x = -x + 3
<h3>
<u>Explanation</u></h3>
- Given the system of equations.

- Solve the system of equations by eliminating either x-term or y-term. We will eliminate the y-term as it is faster to solve the equation.
To eliminate the y-term, we have to multiply the negative in either the first or second equation so we can get rid of the y-term. I will multiply negative in the second equation.

There as we can get rid of the y-term by adding both equations.

Hence, the value of x is 3. But we are not finished yet because we need to find the value of y as well. Therefore, we substitute the value of x in any given equations. I will substitute the value of x in the second equation.

Hence, the value of y is 4. Therefore, we can say that when x = 3, y = 4.
- Answer Check by substituting both x and y values in both equations.
<u>First</u><u> </u><u>Equation</u>

<u>Second</u><u> </u><u>Equation</u>

Hence, both equations are true for x = 3 and y = 4. Therefore, the solution is (3,4)
