Simplify this expression.

2(x - 3) + 4x

Answer:

-0.1

Step-by-step explanation:

Just looking at the expression, -513.5 and 513.5 cancel out because they equal 0. So all you have left is -0.1

Hope this helped! :)

Answer:

n=0

Step-by-step explanation:

Let's solve your equation step-by-step.

3(−10n+9)−3(1+8n)=24

Step 1: Simplify both sides of the equation.

3(−10n+9)−3(1+8n)=24

(3)(−10n)+(3)(9)+(−3)(1)+(−3)(8n)=24(Distribute)

−30n+27+−3+−24n=24

(−30n+−24n)+(27+−3)=24(Combine Like Terms)

−54n+24=24

−54n+24=24

Step 2: Subtract 24 from both sides.

−54n+24−24=24−24

−54n=0

Step 3: Divide both sides by -54.

−54n/-54=0/−54

n=0

Answer:

(x+6)(x+2)(x-5)(x-7)

Step-by-step explanation:

step 1: ((((x4)-(4•(x3)))-72x2)+136x)+420

step 2: ((((x4) -  22x3) -  72x2) +  136x) +  420

step 3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  2  and  6

                    x2 + 2x + 6x + 12

step 4: Add up the first 2 terms, pulling out like factors :

                   x • (x+2)

             Add up the last 2 terms, pulling out common factors :

                   6 • (x+2)

step 5: Add up the four terms of step 4 :

                   (x+6)  •  (x+2)

            Which is the desired factorization

Answer:

5/8

Step-by-step explanation:

1 inches in fraction form would be 8/8 inches, and the button is 3/8 inches, so a 1 inch button is 5/8 inches longer than a 3/8 inch button

Answer:

5/8

Step-by-step explanation:

it takes 5 more inches to get to 1 inch from 3/8

Answer:

± 1.13432%

between 23.966% and 26.234% households in the population who tuned into the final episode of ​"When Will it End question mark​"

Step-by-step explanation:

Given that:

Sample size (n). = 5613

Proportion (p) = 25.1% = 0.251

Margin of Error can be obtained using :

MOE = z * √p * (1 - p) / √n

Zscore at 95% confidence interval = 1.96

1 - p = 1 - 0.251 = 0.749

Hence,

Margin of Error :

1.96 * √0.251 * 0.749 / √5613

1.96 * (0.4335885 / 74.919957)

= 0.0113432

= ± (0.0113432) * 100%

= ± 1.13432%

B.) between (25.1 - 1.134)% = 23.966% and 25.1 + 1.134)% = 26.234% households in the population who tuned into the final episode of ​"When Will it End question mark​"

Margin of Error (MOE) is a function of the critical value. We will choose a confidential interval of 95 %.

Solution is:

a) MOE = 0,011

b) We can affirm with 95 % of confidence that the porcentage of TV households in the population watching th final  episode of " When ...

would be between  25,1 - 0,011  and  25,1 + 0,011

In our question we got:

Sample size    n = 5613

p = 25.1 %    ( positive events expressed as porcentage )

q = 1 - p     q = 1 - 0,251    q = 0,749

According to the size of the sample, and the fact that

q×n    and   p×n   are both    q×n > 10   p×n > 10

We are in condition to apply the approximation of the binomial distribution to normal distribution and use table z scores

CI   = 95 %    then  confidence level   α = 5 %    α/2 = 0,025  and fom z-table we get the critical value

z(c) = 1,96

Now to find MOE

MOE = z(c)×√(p×q/n)  ⇒ MOE = 1,96 × √ ( 0,251×0,749)5613

MOE = 1,96 × 0,005787

MOE = 0,011

Answer:

42,557 ft²

Step-by-step explanation:

Area of the parallelogram = 2×(Area of ∆)

Area of parallelogram = 2×(½×a×b×sin(θ))

Where,

a = 120 ft

b = 530 ft

θ = 138°

Plug in the values into the formula

Area of parallelogram = 2×(½×120×530×sin(138))

= 120×530×sin(138)

= 42,557 ft² (nearest square foot)

Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

For example 4/2 = 2

Given expression as :

⇒ [tex]4\dfrac{2}{7} + 2\dfrac{9}{14}[/tex]

⇒ (28 + 2)/7 + (28 + 9)/14

Answer:

So answer is [tex]\frac{10+x}{y-3}[/tex]

Step-by-step explanation:

We are given with quotient of 10 plus x and y minus 3.

So, we can write 10 plus x as 10+x and y-3

So, quotient of 10+x and y-3 is [tex]\frac{10+x}{y-3}[/tex]

Answer:The last option

Step-by-step explanation:the absolute value bars make it positive but the negative on the outside of those bars make it negative, this -|3|=-3 and -|2|=-2. Furthermore, the double negative on the last two dots make a positive, thus -(-2)=2 and -(-3)=3. With this in mind it is -3,-2,2,3 and -|3|,-|2|,-(-2),-(-3)

Both angles will add up to 180°, so we set up a equation where (4x - 19)° and (6x + 9)° equal 180°.

[tex]4x - 19 + 6x + 9 = 180\\\\10x - 10 = 180\\\\10x = 190\\\\x = 19[/tex]
