Answer:

$\Huge\boxed{8x+6}$

Step-by-step explanation:

First, used distributive property.

DISTRIBUTIVE PROPERTY

A(B+C)=AB+AC

4x(4-2)+6

Subtract the numbers from left to right.

4x(4-2)

4-2=2

4*2x

Then, multiply.

4*2=8

4x*2x=8x

=8x+6

In conclusion, the final answer is 8x+6.

Is the triangle an equilateral triangle

solong [7]

It is not an equilateral triangle. To prove this, you must solve for x. I found x by setting 2x+5.2 = 3x+1.2 to get x=4. Then I plugged 4 into equation to see if they were equal. 2(4)+5.2= 13.2 and 3(4)+1.3=13.2 but 2(4)+6.2=14.2. This allows us to conclude that the triangle is not equilateral because all of the sides are NOT congruent. Hope that helped:))

Solve 2(9-x) = 3 ( x +16 )

andreyandreev [35.5K]

Answer: x=-6

Step-by-step explanation:

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

2(9−x)=3(x+16)

Step 1: Simplify both sides of the equation by distribution

$2(9-x)=3(x+16)\\(2)(9)+(2)(-x)=(3)(x)+(3)(16)\\18+-2x=3x+48\\-2x+18=3x+48\\$

Step 2: Subtract 3x from both sides.

$-2x+18-3x=3x+48-3x\\-5x+18=48$

Step 3: Subtract 18 from both sides.

$-5x+18-18=48-18\\-5x=30$

Step 4: Divide both sides by -5.

$\frac{-5x}{-5} =\frac{30}{-5} \\x=-6$

Geometry math question please help

denis-greek [22]

In parallelogram the opposite sides are equal. Therefore we have the equation:

$8a-4=6a+10\ \ \ |+4\\\\8a=6a+14\ \ \ |-6a\\\\2a=14\ \ \ |:2\\\\\boxed{a=7}$

In the parallelogram, the sum of measures of the angles at one side is 180°. Therefore we have the equation:

$(18b-11)+(9b+2)=180\\\\(18b+9b)+(-11+2)=180\\\\27b-9=180\ \ \ |+9\\\\27b=189\ \ \ \ |:27\\\\\boxed{b=7}$

Answer:

c = a + b → c = 7 + 7 = 14

A. 14

In your own words, explain HOW to find the standard deviation of this data set.In your own words, explain HOW to find the standa

mr Goodwill [35]

Answer:

The answer is below

Step-by-step explanation:

The standard deviation formula is as follows:

$SD = \sqrt{\frac{Sum|x - m|^2}{N} }$

where sum means "sum of", x is a value of a data set, m is the mean of the data set, and N is the number of data.

The standard deviation formula may seem confusing, but it will make sense after we break it down. In subsequent sections we will explain an interactive example, step by step. Here's a quick preview of the steps we're about to follow:

Step 1: Calculate the mean with the data from the graph.

Step 2: Calculate the square of the subtraction between the mean and each data (that is, each x).

Step 3: add the values that resulted from step 2.

Step 4: divide by the number of data.

Step 5: take out the square root.

And in this way you can obtain the standard deviation
