How solve step by step -5р - 9 + 8р = 36

Answer:

Step-by-step explanation:

Use Foil method

(2x  + 4)(x -1) = (2x*x)+ (2x *(-1)) + 4*x + 4*(-1)

                    = 2x² - 2x  + 4x - 4   {Combine like terms}

                    = 2x² + 2x - 4

The equation which is results from taking the square root of both sides of the provided equation is,

[tex](x+9)=\pm5\\[/tex]

A square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.

Let a number is a. Then this number in the form of square root can be written as,

[tex]a=\sqrt{a}\times \sqrt{a}[/tex]

The given algebraic equation in the problem is,

[tex](x+ 9)^2 = 25[/tex]

Take the square root, in both sides,

[tex]\sqrt{(x+ 9)^2} = \sqrt{25}\\\sqrt{(x+ 9)^2} = \sqrt{5^2}[/tex]

Cancel out the square root with the square of the number as,

[tex](x+9)=\pm5\\[/tex]

Hence, the equation which is results from taking the square root of both sides of the provided equation is,

[tex](x+9)=\pm5\\[/tex]

Perimeter of the given polygon is equals to 64cm.

"Perimeter is defined as the total distance around the given shape."

Theorem used

Tangents drawn from a exterior point of a circle have equal length.

According to the question,

As shown in the diagram,

P, Q, R, and S are exterior points of a circle through which tangents are drawn.

Given,

Length of tangent PA = 13cm

Length of tangent SA= 9cm

Length of tangent RC = 4cm

Length of tangent QC =6cm

As per  stated theorem we get,

Length of tangent PB = 13cm

Length of tangent SD 9cm

Length of tangent RD = 4cm

Length of tangent QB =6cm

Perimeter of a given polygon = 13 +13 +9+9+4+4+6+6

                                                 = 64cm

Hence, perimeter of the given polygon is equals to 64cm.

Answer:

420 $40 tickets.

Step-by-step explanation:

Here is the explanation.

1. As 700 tickets cost a total of $33600, the average cost of each ticket is $48.

2. As there are 700 total tickets with each costing $40 or $60, we can use the total cost ($33600) to define the amount of each ticket.

3. If there were to be 420 $40 tickets, there will be 280 $60 tickets.

4. This means that the cost of each price of tickets ($40 and $60) will be distributed evenly among the total price, each costing $16800.

5. 420 x 40=16800 280x60=16800

6. There are 420 $40 tickets sold at the concert.

THIS IS THE COMPLETE QUESTION BELOW:

Karen has a red ribbon that is 18 feet long and a blue ribbon that is 12 feet long. She wants to cut both ribbons into pieces that are all the same length and she wants no ribbon leftover when she is done. What is the greatest length in feet, of each piece of ribbon that she can cut?​

Here the question is only talking about the GREATEST COMMON FACTOR that exist between 12 and 18. Since we are told that She wants to cut both ribbons into pieces that are all the "THE SAME LENGHTH"

For the ribbon that of 18 feet long, it can only be cut into 3pieces of equal Lenght i.e(18/6)= 3 pieces

For the ribbon that of 12 feet long, it can only be cut into 2pieces of equal Lenght i.e(12/6)= 3 pieces

Therefore the greatest common factor which divide both 12 and 8 is 6. which means 6 is the greatest length in feet, of each piece of ribbon that she can cut

Answer:

Proper fractions with a denominator of 6: 1/6, 2/6, 3/6, 4/6, 5/6.

Step-by-step explanation:

A proper fraction means that the numerator is less than the denominator.

Examples of this are 1/3, 3/4, 2/7.

Since the denominator must be 6, hence the answers are 1/6, 2/6, 3/6, 4/6, 5/6.

We know that the number line is in 12ths. In addition, we know that 6ths are  1/2 of 12. Thus, we put a proper fraction on every other line on the number line.

Answer:

x=57

Step-by-step explanation:

Since the angles 'x' and '2x+7' add up to a supplementary angle (straight line)

we can then say;

[tex]x + 2x + 9 = 180[/tex]

[tex]3x = 180 - 9[/tex]

[tex]3x = 171[/tex]

[tex]x = \frac{171}{3} = 57[/tex]

Answer:

I think 57

Step-by-step explanation:

x+2x+9=180

3x+9=180

3x=180-9

3x=171

x=57

Answer:  A segment AB with Endpoints A (-8, 4) and B (2,4) is a horizontal line segment with (-3,4) as the midpoint.

A segment CD with endpoints C(-3,9) and D(-3,-1) will create a vertical line segment with (-3,4) as the midpoint.

A line segment FG with endpoints F (-6,0) and G(0,8) is a diagonal line with a slope of 4/3 and its midpoint is (-3,4)

Step-by-step explanation: For a horizontal or vertical line segment, choose the x-value or the y value of the midpoint. subtract 5 to get the lower endpoint, add 5 to get the higher endpoint. Keep the other coordinate the same.

The diagonal line segment is based on the hypotenuse of a triangle with side lengths corresponding to the Pythagorean Triple 3,4,5  Add and subtract 3 to the x-value od the midpoint, add and subtract 4 to the y value of the midpoint and the hypotenuses will extend 5 units in both directions from the midpoint.
