Positive because two negative signs would make it a positive. The answer would be 7. If you had a positive 3 and a negative 4 it would make it negative (bigger number) If you had a positive 4 and a negative 3, it would be positive (bigger number yet again)
If I'm wrong I'm sorry XD I haven't gone this in years.
Answer:When copying existing spreadsheet data to a Word document, you need to select the entire worksheet.
Step-by-step explanation:
Answer:
Part A: x^2 + 5x - 8
Part B: 5x^3 + 3x^2 - 6x + 5
Step-by-step explanation:
Part A:
To find the total of side 1 and 2, add the two expressions which represent each side. Combine like terms to simplify.
3x^2 − 2x − 5 + (7x - 2x^2 − 3)
3x^2 - 2x^2 -2x + 7x -5 + -3
x^2 + 5x - 8
Part B:
To solve for the third side of a triangle using its perimeter, subtract the lengths of two of its sides from its perimeter. The perimeter is 5x^3 + 4x^2 − x − 3. Subtract 3x^2 − 2x − 5 and 7x - 2x^2 − 3. The remaining expression is the third side. Combine like terms to simplify.
5x^3 + 4x^2 − x − 3 - (3x^2 − 2x − 5) - (7x - 2x^2 − 3)
5x^3 + 4x^2 - x - 3 - 3x^2 + 2x + 5 - 7x + 2x^2 + 3
5x^3 + (4x^2 -3x^2 + 2x^2) + (-x + 2x - 7x) + (-3 + 5 + 3)
5x^3 + 3x^2 - 6x + 5
Answer:
The answer is 3x +y^3

Step-by-step explanation:
90° + 2x-2 + x+5 = 180° [Angle sum property of triangle]
=> 90 + 2x + x - 2 + 5 = 180°
=> 3x + 93 = 180
=> 3x = 180 - 93
=> 3x = 87
![= > x = \frac{87}{3}](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20x%20%3D%20%20%5Cfrac%7B87%7D%7B3%7D%20)
=> <u>x = </u><u>29</u><u> (Ans)</u>
