Someone help me with my question.

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

For what values of the variable x is the expression square root of 7x+14+ square root of 7-x a real number?

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
