Which one is false ????

Answer:

x-2

Step-by-step explanation:

(x+2)× ___=(x+2)(x-2)

___=(x+2)(x-2)/(x+2)

___=x-2

The polynomial which should be filled in the blank is (x - 2).

Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.

Given that,

x² - 4 = (x + 2) (x - 2).

We have to find the blank space.

By commutative property, the other side is also equal.

That is,

(x + 2) (x - 2) = x² - 4

Hence the correct option is (x - 2).

Answer:

60 i think

Step-by-step explanation:

109-180= 71

u=71

71+49=120

120-180=60

109 is on a straight line with an interior angle of a triangle, so 180 - 109 = 71 degrees.

Add two known interior angles (71 + 49) together and you get 120 degrees.

Subtract 120 from 180 (since 180 is the sum of all three interior angles of a triangle) and you get 60 degrees.

Answer:

y = 2x² + 12x + 71

Answer:

53°

Step-by-step explanation:

not sure what you mean by nearest degree but use the cosine ratio to get the answer.

in ΔCDE we have the hypotenuse and adjacent side so use cosine ratio : cos C= 45/75

<C=cos^1 (45/75)

<C= 53°

Answer:

50%

Step-by-step explanation:

5 question is what percentage of 10 question

Step 1: Divide 5 by 10

5/10 = 0.5

Step 2: multiply 0.5 by 100

0.5 × 100

= 50%

Therefore, percentage of 5 questions out of 10 questions is 50%

Answer:

50%

Step-by-step explanation:

5 is half of 10

50 is half of 100

Answer: 135.2 °F

Step-by-step explanation:

The temperature decreases at a rate of 2.3 °F per minute.

This means that in 25 minutes, the temperature would have reduced by:

= 2.3 * 25

= 57.5°F

If the original temperature was 192.7 °F, the temperature after 25 minutes will be:

= 192.7 - 57.5

= 135.2 °F

Solution :

Here, we are interested to study if the treatments have any effect on going tumor or not. Actually, this is model is an ANOVA one way layout with a treatment 'drug'.

In this kind of model or ANOVA model, we take the negative statement as our null hypothesis i.e.,

[tex]$H_0:$[/tex] There is no difference in the distribution of tumors states across the three  statements.

Therefore, alternative hypothesis would be :

[tex]$H_a:$[/tex] There is a difference in the distribution of tumor states across the three treatments.

So the correct option is (B).

Answer:

taco:  $1.49 each

burrito:  $1.79 each

Step-by-step explanation:

Let b = cost of one burrito

     t =  cost of one taco

(1)     3b  + 4t  = 11.33              (2)     9b + 5t = 23.56

Multiply (1) by -3 and add to (2)     -9b - 12t = 33.99

                                                              - 7t = - 10.43

                                                                  t = 1.49

       3b + 4(1.49) = 11.33

          3b + 5.96 = 11.33

                  3b = 5.37

                    b = 1.79

Answer:

35 , 36 , 37

Step-by-step explanation:

Let the consecutive integers be x, (x + 1) , (x +2)

x + x + 1 + x +2 = 108

x + x + x + 1 + 2 = 108          {Combine like terms}

     3x + 3   = 108          {Subtract 3 from both sides}

             3x = 108 - 3

            3x = 105            {Divide both sides by 3}

              x = 105/3

               x = 35

The three integers are, 35 , 36 , 37

Answer:

.975 mi²

Step-by-step explanation:

Hello There!

Formula for area of a triangle [tex]A =\frac{1}{2}bh[/tex]

where b = base and h = height

the dimensions of the triangle shown are b = 1.5 and h = 1.3

given the dimensions all we have to do is plug in the values into the formula

so

[tex]A=\frac{1}{2} 1.3*1.5\\1.3*1.5=1.95\\\\\frac{1.95}{2} =0.975[/tex]

so we can conclude that the area of the triangle is

.975 mi²
