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>

Answer:
Area = 168m^2
Step-by-step explanation:
Area of triangle = 1/2×base×height
Area = 1/2bh
= 1/2(8+16)(14)
= 168m^2
Answer:
x= -4
3/6 is 1/2 so -2/4 is equal to one half
;) you can do it.
So when x = -1, you just substitute the variable x to -1.
"4x" means 4 times x, so when x is replaced to -1, that would be 4 times -1.
f(-1) = 4(-1) = -4
So the value of function at x = -1 would be -4.
Hope this helps.
Answer:
1/2
Step-by-step explanation:
4/9 is .444
1/2 is .5
1/3 is .3333
4/9 is closer to being 1/2 than 1/3
