Answer:
10: -11n^5
12: 6k^2 -6k+7
Step-by-step explanation:
Ok so what your gonna do is add or subtract the ones with the same exponent.
so -15+4= -11 since they are both n^5 you can add them so your answer is:
-11n^2
now you have 8k^2-k-5k+7-2k. so you are gonna rearrange them so the same exponents are together.(keep the sign in front in front, if no sign it is positive)
8k^2-2k^2-5k-k+7
add like exponents
6k^2-6k+7
Answer:
Perimeter = 2 ( l + w )
if u r given for rectangle thats the formula
Answer:
Step-by-step explanation:
Coordinates of Point b
b lies on the circle whose equation is 
Comparing with the general form a circle with center at the origin: 
The radius of the circle =17 which is the length of the hypotenuse of the terminal ray through point b.
For an angle drawn in standard position through point b,
x=-8 which is negative
y=15 which is positive
Therefore, the angle is in Quadrant II.
Answer:
1. x less than or equal to 1/3
2. x is less than 1
3. x is greater than 6
4. x is less than -2
Step-by-step explanation:
I think the answer could be A but I'm not so sure because at first Kayla has 6 boxes with x amount of books in the boxes with four left over so the equation would be 6x+4= number of books. So if she then replaces the now five boxes with x amount of books in them and adds four books to each of the five boxes you get 5x+4=number of books so it all equals out to the same number of books on both sides of the equal sign for 6x+4=5x+4
