what is the value for x if the perimeter is 45

Answer:

The product of its roots is 6.

Step-by-step explanation:

Let [tex]m\cdot x^{2}-(6\cdot m +1)\cdot x+(m^{3}+m^{2}+4) = 0[/tex], all roots are calculated by Quadratic Formula:

[tex]r_{1} = \frac{6\cdot m +1 + \sqrt{(6\cdot m + 1)^{2}-4\cdot m\cdot (m^{3}+m^{2}+4)}}{2\cdot m}[/tex] (1)

[tex]r_{2} = \frac{6\cdot m +1 - \sqrt{(6\cdot m + 1)^{2}-4\cdot m\cdot (m^{3}+m^{2}+4)}}{2\cdot m}[/tex] (2)

According to statement, we know that:

[tex]r_{1}+r_{2} = 7[/tex] (3)

By applying (1) and (2) in (3), we have the following expression:

[tex]\frac{6\cdot m +1}{m} = 7[/tex]

[tex]6\cdot m + 1 = 7\cdot m[/tex]

[tex]m = 1[/tex]

If we know that [tex]m = 1[/tex], then the roots of the polynomial are, respectively:

[tex]x^{2}-7\cdot x +6 = 0[/tex]

[tex]r_{1} = 6[/tex]

[tex]r_{2} = 1[/tex]

And the product of the roots is:

[tex]r_{1}\cdot r_{2} = 6[/tex]

The product of its roots is 6.

Answer:

1. No, Lin is incorrect. If you change both numbers to regular notation, you get that Panama has 4,000,000 residents, and Thailand has 70,000,000 residents. 4 million times 20 is 80 million, not 70 million.

2. 10^8. You need to put 10 to the 8th power because 1 × 10^7 is too little, so it is the next power to use that isn't too small

3. Label each increment 10^7, 2 × 10^7, 3 × 10^7... 9 × 10^7, 10^8.

4. Panama's point would be located 2/5 of the way between 0 and 10^7. Peru's point would be located 1/5 of the way between 3 × 10^7 and 4 × 10^7. Thailand's point would be located right on 7 × 10^7.

Answer:

I think its (2, 1) .

Step-by-step explanation:

the 2 represents the x axis

the 1 represents the y axis

Answer:

final answer is 21

Step-by-step explanation:

since x+y=7 and xy=10

2+5=7 and 2(5)=10

so,

(5)3=15  

(2)3=6

15+6= 21

Hey there!

The correct answer is 50 degrees.

To do this, we can figure out all the angles in the triangle. We know one angle: 45 degrees. To find the angle above that angle, we can use the 95 degrees and use linear angles to figure out that missing angle.

A linear pair adds up to 180 degrees, which means that 95 + (missing angle) = 180. 95 + 85 = 180. Therefore, we have two of the three angles in the triangle.

In a triangle, the number of angles adds up to 180 degrees, which means that 45 + 85 + (angle across from x) = 180. 45 + 85 + 50 = 180.

Now we have all the angles in the triangle.

With that information, we can use vertical angles to solve for x. If there are two lines that intersect, the angles opposite eachother are always equal. The angle opposite of x is 50; therefore x is equal to 50 degrees.

Have a terrificly amazing day! :D

Answer:

x = 1/2QN^2

Step-by-step explanation:

Step-by-step explanation:

This would be the point of intersection.

If you are not given the graph, make the equations equal since they are both y = ____.

x + 3 = x - 1

  -3         -3

x = x - 4

-x  -x

-2x = -4

/-2     /-2

x = 2

So the answer would be D) (2,1)

Answer:

⅜ or ⅗

Step-by-step explanation:

I say ⅜ because of how many variables you can take into account 3 different colors, and a 2 sided coin, lastly 3 different numbers. So in total that is 8 possible variables and the 3 being blue, heads, and landing on 1.

Now I say ⅗ because of this perspective on the variables. You have the 3 colors, and your two sided coin but thing here is that the 1 is basically another color so the question is technically asking for the probability of spinning blue, landing on heads and landing on red in a sense.

Go with your gut though between those 2

Answer:

Step-by-step explanation:

    - 50 + (5 / 13)p         this says negative 50 plus 5/13 times p

if p = -26                      what does this epression evaluate to?

- 50 + (5 / 13) × p      p = -26      substitute the value of p into the expression

- 50 + (5 / 13) × (-26)      

- 50 + (5 (-26) / 13)                 I just rewrote the expression to make it clearer

                                               that the -26 in -26/1 and the  5 in 5 / 13    are

                                              both in the numerator over denominator 13

 - 50 + (5 (-26) / 13)              -26 / 13  evaluates to -2

 -50  + (5)(-2)    

 -50  + (-10)

 -50 - 10

 -60                

So we take 6 out of each term so it is [tex]6(4+3v)[/tex] hope this helped.

Answer:

$1100 approx

Step-by-step explanation:

Given data

SImple interest = $55

Time= 5 months in years = 5/12= 0.42 years

rate= 12%

Let the sum be P, that is the principal

The expression for the interest is given as

SI=PRT/100

substitute

55= P*12*0.42/100

Cross multiply

5500=5.04P

P= 5500/5.04

P= 1091.2

Hence the Principal is $1100 approx

I'm sorry, but what exactly are the expressions?

If you comment the expression under my answer, I'll edit my answer and actually answer it.

But nobody can answer an expression that doesn't exist-

gf(x) = g(x^-1) = x^2 + 6x - 8

f(x) = 2x - 10

gf(x) = 6 ( 2x - 10) - 8

gf(x) = 12x- 60 - 8

gf(x) = 12x -68

gf(5) = gf(x) = 12x - 68

gf(5) = 12(5) - 68

gf(5) = 60 - 68

gf(5) = -8

Answer:

58

Step-by-step explanation:

To get the average, you add all of the numbers and then divide by the amount of numbers.

51 + 70 + 97 + 63 + 50 + 31 + 59 + 51 +59 + 50 = 581.

581 ÷ 10 = 58.1

Then, rounding 58.1 is 58
