My work shown is how to get x. now that you have x plug it into the equation.
To test your answer add both 51 and 39, and you should get 90 (the measurement of a right angle)
You convert inches into centimeters
2.54*1.5=3.81
The answer to this question is 3.81
There are an infinite number of negative numbers that aren't integers. This is because integers include whole numbers with negative signs, such as -5 and -7. However, a negative fraction, decimal, rational number, or irrational number would be considered negative numbers that aren't integers. Remember, "numbers" generally means all possible values, and numbers aren't limited to integers.
