C would be the answer as
is the same thing as x * x * x * x.
A knitter with 14 skeins of yarn can make 7 scarves
Explanation:
We can use a proportion to solve this
4 skeins of yarn
-----------------------
2 scarves
That is the information we know. What we want to do is find out how many scarves for 14 skeins of yarn, like this
4 14
-- = ---
2 ?

x3.5
4 14
-- = ---
2 7
x3.5
Answer:
A. x=4 and x= -10
Step-by-step explanation:

x^2 +6x -40
(x-4)(x+10)
x-4 = 0
x+10 = 0
x= 4
x=-10
