Simplify x^2-9x-22/x-11
OleMash [197]

Answer:

x^2-11/-8x

Step-by-step explanation:

We can solve this equation easily by using PEMDAS, or order of operations.

<u>Parenthesis</u>

<u>Exponents</u>

<u>Multiplication>Division (Depends on which comes first left to right)</u>

<u>Addition>Subtraction (See multiplication>division)</u>

Now that we know the order of the operations, we can solve.

First, we cant solve for x^2 because we dont know the value of x, so well leave that alone. Same with 22/x. All we can do is use the commutative property.

So our equation is now x^2-11/-8x

Hope this helps!

F is between E &amp; G e f equals x - 7 + e g equals 4x + 3 find f g
navik [9.2K]

Answer: FG = 3x + 10

<u>Step-by-step explanation:</u>

EF + FG = EG             <em>Segment Addition Postulate</em>

x-7 + FG = 4x+3         <em>Substitution</em>

 -7 + FG = 3x + 3       <em>Subtraction Property of Equality</em>

        FG = 3x + 10      <em>Addition Property of Equality</em>

In any circle of radius R, how many arcs with lengths R fit into the circumference?
xenn [34]

<h2>~<u>Solution</u> :-</h2>

If we take the radius of a circle be <u>R</u>. Then, we can define that,

$ R = x $

Hence,

Arcs will be as $ 4x $. As,

A circle can be divided into four parts according to the radius.

Hence, we know that,

x \times 4

\mapsto \: 4x

  • Hence, <em>according to the radius R</em>, a circle can have <u>4 arcs</u>.
