Nina [5.8K]

Answer:

78 79 80

Step-by-step explanation:

Let the smallest number = x

Let the next number = x + 1

Let the largest number = x + 2

x + x + 1 + x + 2 = 237 Add together to get the equation

3x + 3 = 237 Subtract 3 from both sides.

3x + 3 - 3 = 237 - 3 Combine the right

3x = 234 Divide by 3

x = 234/3

x = 78

The smallest number is 78

The next number 79

The highest number is 80

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