Answer: - 2x^2 + 4x + 3

Step-by-step explanation:

( -x^2 - 4x - 5) + ( -x^2 + 8x + 8)

Take out parentheses:

- x^2 - 4x - 5 - x^2 + 8x + 8

Write in a way so that like terms are grouped together:

- x^2 - x^2 - 4x + 8x - 5 + 8

Combine 'x^2' terms:

- 2x^2 - 4x + 8x - 5 + 8

Combine 'x' terms:

- 2x^2 + 4x - 5 + 8

Combine integers:

- 2x^2 + 4x + 3

Answer:

27 Chickens and 3 Cows.

Step-by-step explanation:

27*2=54 (chickens), 3*4=12 (cows), 54+12=66.

Answer:

3 cows and 27 chickens?

Step-by-step explanation:

x is the number of cows and y is the number of chicken

x + y = 30

cow has 4 legs and chicken has 2 legs therefore

4x + 2y = 66

simultaneously,

x + y = 30 ⇒ x = 30 - y

substitute x = 30 - y in 4x + 2y = 66

4(30 - y) + 2y = 66

120 - 4y + 2y = 66

120 - 2y = 66

-2y = 66-120

-2y = -54

y = -54/-2

y = 27

x = 30 - 27

x = 3

Answer:

Number of nickels: 14

Number of dimes: 31

Total money: $3.80

Step-by-step explanation:

Let number of nickels be x

Number of dimes is 2x+3

Total coins = 45

So add the number of nickels and dimes and it equals 45

x+2x+3=45

3x=45-3=42

x=42/3=14 nickels

Substitute the value of x=14 in 2x+3 to find number of dimes

2(14)+3=28+3=31 dimes

Total money is 14 nickels + 31 dimes

Nickels = 0.05 and dimes is 0.10

14(0.05)+31(0.10)=0.7+3.1=3.8

[tex]k (3x^3 + 8x - 2) = 12x^3 + 32x - 8[/tex]

Step-by-step explanation:

Set up the composite result function.

k (F (x))

Evaluate k (F (x)) by substituting in the value of into.

[tex]k (3x^3 + 8x - 2) = 4 (3x^3 + 8x - 2)[/tex]

Apply the distributive property

[tex]k (3x^3 + 8x - 2) = 4 (3x^3) + 4 (8x) + 4(-2)[/tex]

Simplify

       Multiply 3 by 4.

            [tex]k (3x^3 + 8x - 2) = 12x^3 + 4 (8x) + 4(-2)[/tex]

       Multiply 8 by 4.

             [tex]k (3x^3 + 8x - 2) = 12x^3 + 32x + 4(-2)[/tex]

      Multiply  4 by -2.

[tex] 8\frac{3}{4} [/tex] cups.

Step-by-step explanation:

From the line plot made by Diego which represents bottle sizes in cups, we can see that the most common size is the bottle having 1¾ cups (there are 5 of this sizes).

If he poured all 5 of this bottle sizes in 1 container, he would have the following:

[tex] 1\frac{3}{4} * 5 = \frac{7}{4}*5 = \frac{35}{4} [/tex]

[tex] = 8\frac{3}{4} [/tex] cups.

Answer and Step-by-step explanation: Law of deduction is a mathematical logic that states the following:

1) If p happens, then q happens;

2) p is true;

Then, a there is a third statement that is

3) q is also true.

In this question,

If a polynomial is prime, then it cannot be factored.

Statement p is that 5x + 13y is a polynomial and is prime, i.e., p is true.

Statement q is that "it cannot be factored"

Therefore, 5x + 13y cannot be factored.

The law of detachment is used to confirm or refute a claim.

The true statement is: 5x + 13y cannot be factored

The law of detachment states that; for statements p and q

(1) If p then q

(2) p

If the above statements are true, then the following statement is true

(3) q

The statements in the question can be represented as:

(1) If 5x + 3y is a polynomial and is prime then it cannot be factored

(2) It cannot be factored

Using the above representations of p and q, as an illustration; the third statement would be:

(3) 5x + 3y is a polynomial and is prime

Since the third statement is true, then we can conclude that

5x + 13y cannot be factored

Answer:

The answer is 40.2

The approximate perimeter of the rectangle ABCD plotted below is 40.24 units.

The given coordinates are B(4,5), A(-6,0), C(8, -3) and D(-2, -8).

We need to find the perimeter of the rectangle ABCD by plotting the coordinates on the graph.

The formula to find the perimeter of the rectangle is 2(Length+Breadth).

By using the distance formula find the length and breadth of a rectangle.

That is Distance = [tex]\sqrt{(x_{2}-x_{1} )^{2} -(y_{2}-y_{1} )^{2}}[/tex] units.

Now, AB=[tex]\sqrt{(4+6)^{2}+(5-0)^{2} } =\sqrt{125}[/tex]=11.18 units

BC=[tex]\sqrt{(8-4)^{2}+(-3-5)^{2} } =\sqrt{80}[/tex]=8.94 units

Now, Perimeter=2(11.18+8.94)=40.24 units

Therefore, the approximate perimeter of the rectangle ABCD plotted below is 40.24 units.
