Answer: x = 2

Step-by-step explanation: If g(x) = 3x + 14, and g(x) = 20 also, you first can set 3x+14 = 20. To find the value of x, you want to isolate the variable. You can subtract 14 from both sides to get 3x = 6. Finally, to find out the value of x, divide 3 from both sides. This leaves you with x = 2. You can check this by plugging two back into the original equation 3 times 2 = 6, and 6 plus 14 equals 20.

Factor completely x³ + 6x² - 3x – 18
$- 6 + 6( - 6)^{2} - 3( - 6) - 18 \\ - 6 +6 \times 6 ^{2} + 18 - 18 \\ - 6 + 6 ^{3} + 18 - 18 \\ - 6 + 216 \\ 210$
with a root of x = -6

the answer is 210

Answer:

Step-by-step explanation:

52 + 27 = angle 1 (sum of two interior opposite angle is equal to the exterior angle formed)

79 = angle 1

angle 2 + 71 = 92 degree (sum of two interior opposite angle is equal to the exterior angle formed)

angle 2 = 92 - 71

angle 2 = 21 degree
