Circumference of a circle
<h3>
Answer: a^2 - b^2 = (a-b)(a+b)</h3>
The order of the factors does not matter.
So (a-b)(a+b) is the same as (a+b)(a-b)
This is known as the difference of squares factoring rule.
You can FOIL out (a-b)(a+b) and you'd get a^2+ab-ab-b^2. Note how the ab terms cancel leaving us with a^2-b^2. This confirms we have the correct factorization.
Solution is where the two lines intersect. When you look at where they meet, it would be (2,6)
The solution is A. (2,6)
Is that all the information they give you ?
F-1(x) = 4
If you supply 3 for the function of F so F(3) =4x then 4x3=12
