Answer:
x + 6 is not a factor of f ( x ) = x³ - 3x² + 2x - 8 because when -6 is substituted into the function, the answer is not 0.
Step-by-step explanation:
→ Substitute x = -6 into f ( x )
( 6 )³ - 3 × ( 6 )² + ( 2 × 6) - 8
→ Simplify
216 - 108 + 12 - 8
→ Simplify further
112
Follow these rules:
Multiply and divide before adding and subtracting.
(1/4)(1/4) = 1/16, so now we have 1/16 - 1/4 ÷ 1/4 ÷ 1/4 ÷ 1/4
1/4 ÷ 1/4 = 1, so now we have 1/16 - 1 ÷ 1/4 ÷ 1/4
1 ÷ 1/4 = 4, so now we have 1/16 - 4 ÷ 1/4
4 ÷ 1/4 = 16, so now we have 1/16 - 16
1 - 256
and this simplifies to -15 15/16, or ------------
16

Answer:
A (I believe)
Step-by-step explanation:
since the part with the triangle is 6 yards, and it looks about half of that whole side, I'm going to assume that that side is 12 yards, and since it's a square each side will be the same length. so multiply 12 and 12 to get 144.
Now divide that by four so you can get the area of a fourth of the square and find the area of the triangle. 144 ÷ 4 = 36
Now divide 36 by 2 to get the area of the little triangle. 36 ÷ 2 = 18
Now divide 18 by 6 to get x. 18 ÷ 6 = 3
In conclusion, the answer should be A.
Hope this helped!!! :3
