Answer:
Step-by-step explanation:
#1 Synthetic method
- 2x³ + x² - 2x - 4 ÷ x + 1 = 2x² - x - 1 rem 3
--------------------------------------
x + 1 | 2x³ + x² - 2x + 4
---------------------------------
-1 | 2 1 -2 4
<u>| - 2 1 1 </u>
2 - 1 - 1 3
#2 Long division
- 3x³ - 5x² - 26x - 8 ÷ 3x + 1 = x² - 2x - 8
--------------------------------------
3x³ - 5x² - 26x - 8 <u>| 3x + 1</u> = x² - 2x - 8
<u>3x³ + x²</u>
-6x² - 26x
<u>-6x² - 2x</u>
- 24x - 8
<u>- 24x - 8</u>

You use it at the end of a sentence and it looks like this! It means like loud
Answer:
15tan 30
Step-by-step explanation:15 tan30°
Remember SOHCAHTOA.
tanθ =
opposite
adjacent
tan30° =
x
15
x = 15 tan30°
<span>f(x) = –10
f(5)=-10
f=</span>-10 divided by 5
f=-2
