Answer:
x³-2x²-22x-21
Step-by-step explanation:
(x+3) (x²-5x-7)
x³-5x²-7x+3x²-15x-21
x³-2x²-22x-21
Answer:
No he is not correct. As the answer would be -2/5 = -0.4 and 5/-2 = -2.5 as the answer is also not opposite.
What's the first and third quartile of -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 7, 7, 7

There are 14 total numbers.
Make a list of the 7 lowest numbers:
-5, -4, -3, -2, -1, 0 , 1
The first quartile is the middle value of the lower half of numbers
Since there are 7 numbers ( odd number), the middle value is the middle number, which is -2
Now make a list of the 7 highest numbers:
2, 3 , 4, 5 , 7, 7, 7
The 3rd quartile is the middle value of the higher half of numbers.
Again because there are 7 numbers ( odd number), the middle value is the middle number, which would be 5.
First quartile = -2
Third quartile = 5
Answer: x^5/x^1 = x^4
y^2/y^2 = 1
so
x^4
