Choose the situation in which the use of approximate numbers is most appropriate.

A. 

Getting an exact number for gravel is difficult because it spills and the ground is not usually perfectly level. Thus it would be okay to estimate the amount needed.

Solve 2x2 + 3x = −8.
77julia77 [94]

Answer:

Final answer iis choice B) x=\frac{-3\pm i\sqrt{55}}{4}

Step-by-step explanation:

2x^2 + 3x =-8

2x^2 + 3x +8 = 0

Compare with quadratic equation ax^2 + bx +c = 0, we get:

a=2, b=3, c=8

Now plug these values into quadratic formula:

x=\frac{-3\pm \sqrt{\left(3\right)^2-4\left(2\right)\left(8\right)}}{2\left(2\right)}

x=\frac{-3\pm \sqrt{9-64}}{4}

x=\frac{-3\pm \sqrt{-55}}{4}

x=\frac{-3\pm i\sqrt{55}}{4}

Hence final answer iis choice B) x=\frac{-3\pm i\sqrt{55}}{4}
