Answer:
Common factor from the two pairs
n2+2n-n-2 or
n(n+2)-1(n+2)
Rewrote in factored form
n(n+2)-1(n+2)or
(n-1)(n+2)
Solution
(n-1)(n+2)
Hello!
Your answer is: 7
(X = "<em>A number</em>")
<em>"11 more than four times a number is 39"</em> in equation form is: 4X + 11 = 39
to solve, first subtract 11 from both sides:
4X = 28
then divide both sides by 4 to get:
X = 7
I hope this helps, and have a nice day!
Answer:
It would be 78.539...
Step-by-step explanation:
So the equation for area is π r^2. We don't have the radius but we have the diameter. Since the radius is always 1/2 of the diameter, simply divide 10/2 to get this.
Now with the radius, it can simply be plugged into the equation for the answer:
π r^2,
π 5^2,
π 25
78.539...
These points show that this is not going to be a linear line. This is actually a parabola.
I find that the function rule is going to be

Only 4 because the only way he cant get a pair is if he picks up a different colour to the previous sock, so by the fourth he will have picked up at two of at least one colour
