Answer:

x = -4 ± 3√6

Step-by-step explanation:

x² + 8x = 38

Complete the square by adding (8/2)² = 16 to both sides.

x² + 8x + 16 = 38 + 16

(x + 4)² = 54

x + 4 = ±√54

x = -4 ± 3√6

The domain of the third piece of the graph is contained in interval <u>B. (12, 20)</u>.

<h3>What is the domain of a graph?</h3>

The domain of a graph consists of all the input values shown on the x-axis.

The input values (domain) are shown on the x-axis, unlike the range, whose output values are shown on the y-axis.

Therefore, the domain comprises the independent variables or values, which can be determined using the function, y = f(x).

Thus, the domain of the third piece of the graph can be determined in interval <u>B. (12, 20)</u>.
