Factor this expression completely.

39x − 52y + 13

Answer:

x = 12

See picture for explanation and steps

Answer:

12

Step-by-step explanation:

These angles are exterior alternate , and thus equal

4x + 16 = 7x - 20

3x = 36

x = 12

Given:

Image of the figure

To find:

The area of the figure.

Solution:

The image is splitted into two shapes.

One is rectangle and the other is trapezium.

Reference image for answer is attached below.

Rectangle:

Length = 10 cm

Width = 2.8 cm

Area = length × width

        = 10 × 2.8

Area = 28 cm²

Trapezium:

Top base = 6 cm

Bottom base = 10 cm

Height = 7.2 - 2.8 = 4.4 cm

Area = [tex]\frac{1}{2} \times(b_1+b_2)\times h[/tex]

        [tex]$=\frac{1}{2} \times(6+10)\times 4.4[/tex]

        [tex]$=\frac{1}{2} \times16\times 4.4[/tex]

Area = 35.2 cm²

Area of the figure = 28 cm² + 35.2 cm²

                              = 63.2 cm²

The area of the figure is 63.2 cm².

Answer:

29/3

Step-by-step explanation:

You use PEMDAS and do the parentheses first:

(5+24)/3= 29/3

Answer:

29/3

or 9.6666666666666666666666666

Step-by-step explanation:

5+24= 29

then divide by 3

Answer:

B) 53%

Step-by-step explanation:

To find the percent divide the number who will vote for Candidate A over the total number of people surveyed

vote for Candidate A/total surveyed

128/240=0.53333

0.53333*100=53.3333%

Rounded to the nearest percent=53%

Hope this helps! :)

Answer:

20

Step-by-step explanation:

12/6 = 2

2x10=20

Answer:

x=-1

Step-by-step explanation:

The first step is to expand everything in parentheses.

-2(3x-4)=4(x+3)+6

-6x+8=4x+12+6

Now, combine like terms.

10x=-10

Finally, divide both sides by 10 to isolate x.

x=-1

Answer:It makes 126 copies.

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Start with the 2(x-y) and distribute the 2 to each term

2(x)-2(y)

This would equal

2x-2y

Which matches the second equation making the answer yes.

The pairs of expressions that are equivalent are:

- [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]

- [tex]\( 4(x+y) \)[/tex] and [tex]\( 4y+4x \)[/tex]

- [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]

Let's simplify each expression to see if they are equivalent.

Step 1

1. [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]:

  Simplifying [tex]\( 2(x-y) \)[/tex]:

 [tex]\[ 2(x-y) = 2x - 2y \][/tex]

  Yes, they are equivalent.

Step 2

2. [tex]\( 4(x+y) \)[/tex] and [tex]\( 4y+4x \)[/tex]:

  Simplifying [tex]\( 4(x+y) \):[/tex]

 [tex]\[ 4(x+y) = 4x + 4y \][/tex]

  Yes, they are equivalent.

Step 3

3. [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]:

  Simplifying  [tex]\( (3q-p)(7) \)[/tex]:

[tex]\[ (3q-p)(7) = 21q - 7p \][/tex]

  Yes, they are equivalent.

Step 4

4. [tex]\( 4(2a-3v) \)[/tex] and [tex]\( 8a+6v \)[/tex]:

  Simplifying [tex]\( 4(2a-3v) \)[/tex]:

 [tex]\[ 4(2a-3v) = 8a - 12v \][/tex]

  No, they are not equivalent.

Step 5

5. [tex]\( 8(3x+c)-1 \)[/tex] and [tex]\( 8c+24x-1 \)[/tex]:

  Simplifying [tex]\( 8(3x+c)-1 \)[/tex]:

  [tex]\[ 8(3x+c)-1 = 24x + 8c - 1 \][/tex]

  No, they are not equivalent.

Step 6

6. [tex]\( 4p+3c \)[/tex] and [tex]\( (c+2p)(2) \)[/tex]:

  Simplifying [tex]\( (c+2p)(2) \)[/tex]:

[tex]\[ (c+2p)(2) = 2c + 4p \][/tex]

  No, they are not equivalent.

[tex]\( (3q-p)(7) \)[/tex]

Complete correct question:

Determine whether each pair of expressions is equivalent.

2(x-y) and 2x-2y

4(x+y) and 4y+4x

21q-7p and (3q-p)(7)

4(2a-3v) and 8a+6v

8(3x+c)-1 and 8c+24x-1

4p+3c and (c+2p)(2)

Answer:

B 2/5

F theoretical > experimental

Step-by-step explanation:

P(heads) = numbers of heads/ total

              =8/20 = 2/5

The theoretical (1/2) is greater than the experimental probability

1/2 > 2/5

Answer:

10(4-10m)

Step-by-step explanation:

You have to find something that can go out of both of the numbers.

10 is the highest that i could find.

So you basically have to put the number on the outside of the racks.

Then divide it.

40-100m

÷10 ÷10

whats left is 4-10m

The variable can't be divided with it since it doesn't have another variable to go with.

The expression '40 - 100m' can be factored by finding a common number, which, for 40 and 100, is 20. On factorizing the expression we get: '-20(2 - 5m)'.

The expression '40 - 100m' can be factored by finding a common number that both 40 and 100 can be divided by. This number is 20, but since we also have -100m, we'll use -20. Therefore, the factored form of '40 - 100m' is '-20(2 - 5m)'. Here is the step-by-step process.

Identify numbers that both 40 and 100 can be divided by evenly; in this case, 20.

Factor out the common number from the original expression, which gives '-20(2 - 5m)'.

Answer:

Step-by-step explanation:

a) X + 5 = 11

   Subtract 5 from both sides

   X = 6

b) X - 6 = 8

   Add 6 on both sides

   X = 14

c) 3 + X = 7

   Subtract 3 on both sides

   X = 4

d) 12 = X + 5

   Subtract 5 from both sides

    7 = X or X = 7

Answer:

a) x=6

Sin A= 1-x² is the correct answer.

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².

Given here, Sin C = x/1 and therefore Hypotenuse = 1 and perpendicular =x

thus Base=1-x² by phytogaraen theorem.

Thus Sin A=1-x² /1

Hence, Sin A= 1-x² is the correct answer.

Answer:

Step 1:  Set x to -1 in the first equation

[tex]f(x) = -x^2 + x[/tex]

[tex]f(-1) = -(-1)^2 + (-1)[/tex]

[tex]f(-1) = -(1) - 1[/tex]

[tex]f(-1) = -1 - 1[/tex]

[tex]f(-1) = -2[/tex]

Step 2:  Set x to -1 in the second equation

[tex]f(x) = -x[/tex]

[tex]f(-1) = -(-1)[/tex]

Answer:

14  17/20

Step-by-step explanation:

Convert the mixed numbers to improper fractions first.

Then multiply 33/5 x 9/4

33 x 9=297  

5 x 4 =20

Then convert 297/20 back to a mixed number by dividing

14 x20 =280

Step-by-step explanation:

Let the lengths of sides of the triangle be 3x, 6x and 8x

[tex] \therefore \: 3x + 6x + 8x = 5.1 \: m \\ \therefore \: 17x = 510 \: cm \\ \therefore \: x = \frac{510}{17} \\ \therefore \:x = 30 \: cm \\ \implies \\ 3x = 3 \times 30 = 90 \: cm \\ 6x = 6 \times 30 = 180 \: cm \\ 8x = 8 \times 30 = 240 \: cm[/tex]

Hence, lengths of the sides of the triangle are 90 cm, 180 cm and 240 cm.

Answer:

17.7

Step-by-step explanation:

First off, we do not need to do anything to the 17, it is already set up for a decimal. So we have to find out how much 1/50 is so we divide:

Divide:

1/50=0.02

Multiply by 35:

0.02 times 35= 0.7

Add the 17:

17+0.7=17.7
