Answer:

x = 2

Step-by-step explanation:

Given 2 intersecting chords, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

EB × AE = ED × CE

x(x + 1) = 3 × 2 = 6

x² + x = 6 ( subtract 6 from both sides )

x² + x - 6 = 0 ← in standard form

(x + 3)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 2 = 0 ⇒ x = 2

But x > 0 , then x = 2

What do you think are some of the advantages and disadvantages of a capitalist economic system? Do you feel that the advantages
Tcecarenko [31]
Hello!

Advantages of a capitalist economic system:

• Economic growing and expansion.

• Consumer choice (The consumers get to choose what to consume, which leads to better products and services).

• Efficiency of economics (Goods and services based on demand)



Disadvantages of a capitalist economic system:

• Inequality (A small group of people hold most of the wealth)

• There can be a monopoly of power (a specific enterprise is the only supplier of particular commodity)

• Unemployment

• Social benefit ignored. A free market will ignore externalities.

No, I feel the disadvantages outweigh the advantages, because there are more of them.

MrRa [10]

Answer:

I dont have a direct answer but i think i can help.

Step-by-step explanation:

For example, 2%, read "percent", is two every hundred. When we have 100 liters of water, 2% is 2 liters. If we have 200 liters of water, then 2% is 4 liters. Converting a percentage into a fraction can be done by dividing by 100, following the definition of a percentage.
