The solution set for the equation x - 6x + 10 = 0 is

Oxana [17]

Answer:

{3-i, 3+ i}

Step-by-step explanation:

hello : the equation is : x²-6x+10 =0

because : (3+i)²-6(3+i)+10 = 9+6i+i²-18-6i+10 =9+6i-1-18-6i+10 =0...right

same method for 3-i... (all quadratic equation have two conjugate solution)

A hexagonal pyramid is cut by a plane as shown in the diagram. What is the shape of the resulting cross section?

JulijaS [17]

The shape of the resulting cross section of the hexagonal pyramid in the diagram given is: a hexagon.

<h3>What is Hexagonal Pyramid?</h3>

A hexagonal pyramid is a pyramid with six lateral faces and an hexagonal base.

In the diagram, the plane cuts each of the lateral faces of the pyramid, giving a resultant shape that has 6 sides and angles, which is a hexagon.

Thus, the cross section shape is: a hexagon.

Read the following sentence using mathematical symbols . Twice the difference of X and 2, is -22

Cloud [144]

Answer:

2(x - 2) = -22

Step-by-step explanation:

* Lets explain how to solve the problem

- There are some words we can change it by mathematics symbols

like the sum means (+), the difference means (-), the product

means (×), the quotient means (÷) , one half means 1/2 , triple

means (×3) and so one

- So we can change any word expression to a mathematical

expression

* Lets solve the problem

- The sentence is ⇒Twice the difference of X and 2 is -22

- This sentence represents an equation

∵ Twice means Multiply by two

∵ Difference means subtract

∵ is means equal

- Lets explain the parts of the sentence

∵ Twice the difference

- That means we will make the difference at first and then

multiply the result by 2

∴ Twice the difference of X and 2 means we will subtract 2 from x

and then multiply this difference by 2

∴ Twice the difference of X and 2 represented by 2(x - 2)

∵ Twice the difference of X and 2, is -22 means when we

subtract 2 from x and multiply the result by 2 the answer

will be -22

∴ Twice the difference of X and 2 = -22

∴ 2(x - 2) = -22

* The mathematical symbols of Twice the difference of X and 2,

is -22 is 2(x - 2) = -22
