Horse = x = 1 head and 4 feet
Chicken =y = 1 head and 2 feet
Horse + chicken = x + y = 43 ( total heads)
Horse = 43 - y
4x + 2y = 122
4(43-y) + 2y = 122
Simplify:
172-4y + 2y = 122
Combine like terms
172-2y = 122
Subtract 172 from both sides
-2y = -50
Divide both sides by-2
Y = 25
X + y = 43
X + 25 = 43
X = 18
There are 18 horses and 25 chickens.

the two lines makes it positive, and so 5+6= 11
Answer:
x+2
Step-by-step explanation:
A factor of a polynomial can be thought of as the value of x at which the polynomial is equal to zero.
So, you can use the values in the options given and put them in the polynomial from the question.
for example: try, part a) x-1, here x=1 since the factor is x-1=0
put this value in the polynomial to see if it results to zero.

so this isn't the answer.
now try, part d) x + 2, here, x = -2

you'll see this is the factor!
Answer:
True
Step-by-step explanation:
64 - x^2
Rewriting as
8^2 - x^2
(8-x)(8+x)
This is the difference of squares
