What is the approximate value of x in -2 In (x + 1)-3 = 7? x = -0.993
x = 0.0067
x = -5
x = -6

-0.993

Step-by-step explanation:

ADD 3 and DIVIDE by -2 to get the natural log expression by itself on the left.

Then convert to an exponential equation. Ln means that the base is e (e is a special number,but in fact, just a number)

e^(-5) -1 can be calculated on a calculator. There is usually an e^x button, then enter -5 exponent. Lastly subtract one.

x = -0.993

the discriminant is 64 + 4*1*12 = 112

this is prime.
