Can u answer my question in my profile
2(0) + (0) - 3(0) +4= 4
*My bad
x + 9 = 37
To solve for x bring 9 to the right side by subtracting 9 to both sides (what you do on one side you must do to the other). Since 9 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.
x + 9 - 9 = 37 - 9
x + 0 = 28
x = 28
Check:
28 + 9 = 37
37 = 37
n - 5 = 9
To solve for n you must add 5 to both sides (what you do on one side you must do to the other). Since 5 is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.
n - 5 + 5 = 9 + 5
n + 0 = 14
n = 14
Check:
14 - 5 = 9
9 = 9
Hope this helped!

Answer: Each side of the triangle equals 7.11 centimeters
Step-by-step explanation: The question states that what we have is an equilateral triangle. That’s a triangle with all three sides equal. Having that in mind, if one side measures 2cm for example, then the other two sides measure 2cm as well. Hence if one side of the equilateral triangle measures x (the dimensions are still unknown), then the other two sides each measure x as well. If the perimeter of the triangle is given as 21.33 cm, and each side of the equilateral triangle is x, then
x + x + x = 21.33
3x = 21.33
Divide both sides of the equation by 3
x = 7.11
Therefore, each side of the equilateral triangle equals 7.11 cm
