Help me find x but in only simplified radical form

Answer:

[tex]36n^2+12n+1[/tex]

Step-by-step explanation:

Foil the equation!

1. You see that is to the second power so it means this [tex](6n+1)*(6n+1)[/tex]

2. Then you use the Foil method. First, Outside, Inside, and Last.

3. Combined like terms

4. Answer!

A tip you can use to avoid Foil is this mental math trick: (Keep in mind this only works if the polynomial is being squared.)

1. Multiply the first number by itself = [tex]6n *6n = 36n^2[/tex]

2. Add the first number by itself = [tex]6n+6n = 12n[/tex]

3. Multiply the last number by itself = [tex]1*1 =1[/tex]

4. Combined to form your answer = [tex]36n^2+12n+1[/tex]

NOTE: This is the same thing as a foil but it uses mental math so it takes less time!

Answer:

32b + 12

Step-by-step explanation:

Add up all the values with b in them, so 15 + 5 + 12 = 32. Then, add the whole number. Your simplified answer should be 32b + 12.

Answer:

Step 4 is wrong and so is Step 7

Step-by-step explanation:

In step 4, she would have had to add 8 to both sides.

In step 7, the answer is first of all, wrong, and second of all, it would have been negative 1. (if even 1)

x is supposed to equal -9

Hope I helped :)

Please consider Brainliest :)

Answer:

Step 3 is wrong and step 4 is wrong too.

Step four was she was supposed to ADD 8 not subtract. In step 3, ur not supposed to have 2 operators (ex: operators are division sign, multiplication, subtraction, and addition sign. )

Answer:

x = 4

Step-by-step explanation:

it's important to keep in mind that you can do anything to an equation as long as you do it to both sides, and it will still be equal.

2x + 5 = 13

subtract 5 from both sides of the equation

2x + 5 -5 = 13 - 5

2x = 13 -5

2x = 8

divide both sides of the equation by 2

2x/2 = 8/2

x = 4

The value of x for the equation 2x + 5 = 13 is x = 4.

Given that:

There is an equation in x which is given as,

2x + 5 = 13

It is required to find the value of x.

That is, solve the equation.

It is required to get the equation in such a way that x is on one side and a constant on the other side.

2x + 5 = 13

Subtract both sides by 5.

2x = 8

Divide both sides by 2.

x = 4

Hence the value of x is 4.

Answer:

*I just learned that in probability if a question has 'and' it means you multiply and if it has 'or' it means you add*

1a) 1/6

There are two numbers greater than four (5 and 6). There are 6 possible numbers you can get, so the fraction would be 2/6, or simplified would be 1/3. There are two options you can get when flipping a coin, so the chance of getting a head is 1/2. This is an 'and' problem so multiply 1/3•1/2 and you get 1/6.

1b) 1/4

There are 3 even numbers (2, 4, and 6), so the probability would be 3/6 or simplified to 1/2. The chance of landing on a tail is also 1/2, as there are two possible options. This is an 'and' problem so multiply 1/2•1/2 and you get 1/4.

2) 1/8

Write out your possible results: HHH, HHT, HTH, THH, HTT, THT, TTH, TTT.

3a) 1/8

There are 4 shirt options to choose from. The chance of picking blue is 1/4. There are 2 pant options. The chance of picking black is 1/2. This is an 'and' problem, so multiply 1/4•1/2 and you get 1/8.

3b) 1/4

There are 4 shirt options to choose from. This is an 'or' problem because he can choose an orange shirt OR a red shirt. The probability of picking an orange shirt is 1/4 and the probability of picking a red shirt is 1/4. 'Or' means you use addition so add 1/4+1/4 and you get 2/4 or simplified is 1/2. There are 2 pant options to choose from, so the probability of choosing brown pants is 1/2. Now, this is an 'and' problem, so multiply 1/2•1/2 and you get 1/4.

Answer:

Step-by-step explanation:

The vertical angles theorem states that when two straight lines intersect, they form two sets of linear pairs with congruent angles.

A midpoint divides a line into 2 congruent segments.

The SAS Theorem states that if 2 sides and the included angle of a triangle are congruent to 2 sides and the included angle of another triangle, then the 2 triangles are congruent.

Answer:

Yes

Step-by-step explanation:

If you perform the vertical line test, each row where there is a point only gets hit once, if it got hit twice it would not be a function.

Answer:

So we want to divide  by .

The first thing we are going to do is factor the denominator of the first fraction and the denominator of the second one:

- For our first fraction:

Now we can rewrite our first fraction:

- For our second fraction:

Now we can rewrite our second fraction:

Last but not least, we can express our division as a fraction and simplify:

We can conclude that the result of dividing r+5/ r^2+5r-14 by r^2+4r-21/r-2 is:

Answer:

x + y - 13

Step-by-step explanation:

It has three terms, or numbers or variables

Answer:

option 1

Step-by-step explanation:

A expression that has 3 terms is called trinomial.

x + y - 13  -----> trinomial

If this is a good coin meaning that the head has as many chances as being flipped as a tail then you can expect 48.

There are only two options per flip and thus both sides have an even chance of getting flipped. So each would have half the number of flips to be flipped.

Hope that helped!

= 60 US QUARTS

Answer:

(for the second one)

y = 4x + 10

solution:

so first you have to find the slope, there is an equation for it. it is y2 - y1/ x2 - x1 or just y1 - y2/ x1 - x2 . so input the easiest points. id say f(0) and f(1)

so it will look like

2 - 6/0 - 1

-4/-1

4

so you can now write the equation as

y = 4x + b

now you have to find the y-intercept so input a point. i dont think you should input a point you used to find the slope because you could have made a mistake calculating so lets input f(2)

sooo

18 = 4(2) + b

18 = 8 + b

b = 10

so the function for the second one is y = 4x + 10

Answer: The integers has an absolute value of 53.

Step-by-step explanation:

Given that:

George wrote an integer ;

Let integer = y

Opposite of integer = - 53

From the options given, the best conclusion that must be true is to say George's integer has an absolute value of 53. Because an absolute value clears our doubt of the integer being positive or negative. Also, an absolute value cannot be negative.

Also, an integer of - 53 cannot have an opposite value of - 53

Step-by-step explanation:

there are 5 possible events (01234)- there are 3 favorable outcomes (123)

so that's 3 out of 5 or  3/5 or 60%

The estimated probability of a success is  3/5 or 60%.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

We are given that randomly generated list of integers from 0 to 4 is being used to simulate an event with the numbers 1, 2, and 3 representing a success.

There are 5 possible events (01234)

There are 3 favorable outcomes (123)

Therefore, the estimated probability of a success are; 3 out of 5 or  3/5 or 60%

polyminal

Step-by-step explanation:

A polynomial with integer coefficients that cannot be factored into polynomials of lower degree , also with integer coefficients, is called an irreducible or prime polynomial . Example 1: x2+x+1.

Example 2:

The polynomial

x2−2

is irreducible over the integers. However, we could factor it as

(x−2√)(x+2√)

if we are allowed to use irrational numbers. So the irreducibility of a polynomial depends on the number system you're working in.
