Answer:
x = 130 degrees
Step-by-step explanation:
7-sided polygon = 900 degrees
114 + 138 + 127 + 108 + 142 + 141 + x = 900
770 + x = 900
<u>-770 -770</u>
x = 130

Step-by-step explanation:
Answer:
f(x) = -x³ + 3x² + 4x - 12
Step-by-step explanation:
f(x)=(x+2)(-x+3)(x-2)
Step 1. Use the difference of two squares
(x + 2)(x - 2) = x² - 4
f(x) = (-x + 3)(x² - 4)
Step 2. Long multiplication
x² - 4
<u>-x + 3 </u>
-x³ + 4x
<u> + 3x² - 12</u>
-x³ + 3x² + 4x - 12
f(x) = -x³ + 3x² + 4x - 12
