Which of the following is the reciprocal of the factored form of: x2 - 2x - 8

We are given quadratic x^2-2x-8.

Let us factor it by product sum rule.

According to product sum rule, we need to find the factors of -8 that add upto -2.

If we write all factors of 8, we get 8,4,2 and 1 factores.

So, we could choose -4 and +2.

Because -4+2 = -2 (sum) and -4*2=-8 (product)

x^2-2x-8

Splitting middle term into two terms -4x+2x

x^2-4x+2x−8

Factoring out gcf from each group.

x(x-4) +2(x- 4)

(x + 2)(x - 4)

So, we got factored form of the given euadratic (x + 2)(x - 4).

Reciprocal of it would be .

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
