Answer:
The value of k will be -4
Step-by-step explanation:
We have given polynomial 
It is given that x+1 is factor of the polynomial
And we have to find the value of k
As x+1 is the factor of polynomial so x+1 = 0 that is x = -1 will be the root of polynomial
So if we put x = -1 in the polynomial then the p(-1) will be zero
So 

So the value of k will be -4
First off, nicely done on the exponents. You'd be surprised on how bad some look ,:D

Hello there!
Number 1 is C (11, 4) Image is below
I don't know number 2, so so sorry!
Number 3 is A. 36 The formula for perimeter of a rectangle is (2 * base) + (2 * height)
The base = 13
The height = 5
(5 * 2) + (13 * 2)
10 + 26 = 36
Number 4 is 23 units.
I hope I was of assistance!

So if 1/2 = 18 miles, we want to first find how many sets of 1/2 are in 21/2. We can just do this by dividing.
(21/2) / (1/2) = 21
So we know that there are 21 sets of 1/2 in 21/2, and since 1/2 and 18 are equal, we can say we know there are 21 sets of 18.
We can multiply to find this.
21 * 18 = 378
So two towns are 378 miles apart.
