Hey there mate ;)

Explanation:-

As per question, we can solve by splitting 40 into :-

[tex]10 \: \: \: \: 20 \: \: \: \: 10[/tex]

Proof:

● As its told that the second number must be twice the first number , which means 20 should be the double of 10 (Proved)

● Next it is told that the third number must be the same as first number, which means that 10 must be equal to 10, which is true.

So, the answer is (10 20 10)

Answer:

m= 1/2

Step-by-step explanation:

Answer:

The slope is 1/2

Step-by-step explanation:

Slope of line passing through two points be   (x₁, y₁) and (x₂, y₂)

↬ Slope m = ∆y/∆x

Here,

∆x = x₂ – x₁ = -8 – 12 = -20

∆y = y₂ – y₁ = -4 – 6 = -10

↬ Slope (m) = ∆y/∆x = (-20)/(-10) = 1/2

Thus, The slope is 1/2

Answer:

4(a + 6)

3(x - 4)

Step-by-step explanation:

Factoring is just rewriting an expression into the parts that multiply together to make the original...like if I had a 100 but decided instead to write 4×25 or if I had 25x I wrote 5(5x) .

If you look at your

4a + 24

You're looking for whatever is the same in both pieces (the 4a and also the 24) So there is a 4 in 4a and there is also a 4 "in" 24 (as in 4×6 is 24)

So if you pull out that 4 and throw it up front, whatever is left behind goes into a pair of parentheses.

4 (____ + ____)

4(a + 6)

This is your factored form bc if you multiply that 4 back in you'll get the original expression back again.

4a + 24

= 4(a + 6)

It's like factoring is "un-distributive" property.

Answer:

pretty sure it would be $67 and 10 cent

Answer:

$61.70

Step-by-step explanation:

The tax is 7%. We change that to a decimal, which is 0.07. Then, we multiply 0.07 by the cost of the meal which is $55. We get $3.85. That is the tax.

Tax = $3.85

Now we have to find the tip. We change 15% into a decimal and get 0.15. We then multiply that by the cost of the meal. We get $8.25. That is the tip.

Tip = $8.25

Now we add the cost of the meal, the tax, and the tip.

Total = $67.10

Answer:

A=b(1/2b-1)

112ft^2

Step-by-step explanation:

-Write the equation in factored form: A= b (1/2 b -1 )

-Supposed the base of the flower bed is 16 feet. What will the area be:

b=16 feet

Formula is A=1/2(1/2b-1)

Replace the b with 16

A=1/2 (16)^2 - 16

A=1/2 (256)-16

A=256/2 - 16

A=128-16

A=112 ft^2

The area will be 112 ft^2

To find the gradient of a line you use this equation: Rise / Run

I am assuming this is a graph where both the x and y-axis increase in value by one.

So first of all, you should draw out this graph.

Second, draw a point at each of the given coordinates.

Now, join these points by drawing a right angle triangle. Put simply, draw a line from the point (4, -7) down until it is on the same level as the point (2, -3), then draw a line across.

Finally, measure the length of both these sides and use them in the equation above.

Let's assume the rise (vertical line) and the run (horizontal line) are 5 and 8 respectively. We can do 5/8 to get a gradient which is 0.625.

Answer:

gradient = - 2

Step-by-step explanation:

Calculate the gradient (slope ) m using the gradient formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, - 3 ) and (x₂, y₂ ) = (4, - 7 )

m = [tex]\frac{-7-(-3)}{4-2}[/tex] = [tex]\frac{-7+3}{2}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2

Answer:

47,047

Step-by-step explanation:

x = 5, y = 3, and z = 14 so

5*5 - 6*3 + 20*14*4*3*14

= 25 - 18 + 20*12*14²

= 7 + 20*12*196

= 7 + 240*196

= 47,047

Answer:

Step-by-step explanation:

We know that:

Solution:

Hence, the solution of this problem is 47,047.

Answer:

c=6

Step-by-step explanation:

c+25-19=100

isolate variable...

c+25-19+19=100+19

c+25=119

c+25-25=119-25

c=6

Answer:

94

Step-by-step explanation:

First, we can subtract 19 from 25 on the left:

25 - 19 = 6,

which leaves us with c + 6 = 100.

Subtract 6 from both sides so that c is isolated, so c = 94.

When the acceleration of a car has a negative number (value), it simply means that the car is experiencing a deceleration.

Given the following data:

An average acceleration can be defined as the rate of change of velocity of an object with respect to time and it is measured in meter per seconds square.

In Science, the average acceleration of an object is calculated by subtracting its initial velocity from the final velocity and dividing by the change in time for the given interval.

Mathematically, average acceleration is given by this formula:

[tex]a=\frac{V\;-\;U}{t_f - t_i} [/tex]

Where:  

Note: The parameters given are incomplete and as such the average acceleration cannot be determined in this scenario.

Also, if the acceleration of this car has a negative number (value), it simply means that the car is experiencing a deceleration.

Step-by-step explanation:

We have

[tex] \frac{20x + 9}{25 {x}^{2} + 20x + 4 } [/tex]

Let's factor the denomiator first,

the denomaitor is a perfect square so we get

[tex] \frac{20x + 9}{(5x + 2) {}^{2} } [/tex]

Now, we must think of two fractions that

[tex] \frac{a}{(5x + 2) {}^{2} } + \frac{b}{5x + 2} [/tex]

We use a perfect square term for one fraction, then a linear one for the next, because if we set both of the denomiator to the same factor, we would get a inconsistent system.

So right now, we have

[tex] \frac{a}{(5x + 2) { }^{2} } + \frac{b}{5x + 2} = \frac{20x +9 }{25 {x}^{2} + 20x + 4 } [/tex]

[tex]a + (5x + 2)b = 20x + 9[/tex]

[tex]5b (x)= 20[/tex]

[tex]a + 2b = 9[/tex]

[tex]b = 4[/tex]

so that means that a is

[tex]a + (2)(4) = 9[/tex]

[tex]a + 8 = 9[/tex]

[tex]a = 1[/tex]

So our equation is

[tex] \frac{1}{(5x + 2) {}^{2} } + \frac{4}{5x + 2} [/tex]

Answer:

33°

Step-by-step explanation:

(9 , -1), (4 , 2)

cos α = (x₁ * x₂ + y₁ * y₂) / (√(x₁² + y₁²) * √(x₂² + y₂²))

x₁ = 9,  

x₂ = 4,  

y₁ = -1,  

y₂ = 2

cos α = (9*4 + -1*2) / (√(81+1) * √(16+4))

         = 34/ (√82 * √20)

         ≈ 0.8396

α = 32.91° ≈ 33°

whats the question?                    

You can open those brackets and distribute one brackets content with multiplication to other bracket contents.

The products which result in a sum or difference of cubes is given by:

Option D: [tex](x+4)(x^2 -4x + 16)[/tex]

If there are two terms which are with power 3 (ie cubed), and they both are in addition or subtraction, then that is called sum or difference of cubes for two terms.

Example: [tex]a^3 - b^3[/tex] is difference of cubes.

There is a formula too which you can use in case if you need it which goes like this:

[tex]a^3 + b^3 = (a+b)(a^2 - ab + b^2)\\ \\ a^3 - b^3 = (a-b)(a^2 + ab + b^2)[/tex]

Option A: [tex](x-4)(x^2 + 4x - 16)[/tex]

[tex](x-4)(x^2 + 4x - 16) = x^3 + 64 -4x^2 + 4x^2 -16x - 16x = x^3 +4^3 -32x[/tex]

Thus, not a sum or difference of cubes

Option B: [tex](x-1)(x^2 - x+ 1)[/tex]

[tex](x-1)(x^2 - x+ 1) = x^3 - 1 + x + x -x^2 - x^2 = x^3 - 1 + 2x - 2x^2[/tex]

Thus, not a sum or difference of cubes

Option C: [tex](x + 1) (x - 1)[/tex]

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

It is difference of squares but not of cubes.

Option D: [tex](x+4)(x^2 -4x + 16)[/tex]

[tex](x+4)(x^2 -4x + 16) = x^3 + 64 -4x^2 + 16x + 4x^2 - 16x = x^3 + 64 = x^3 + 4^3\\ (x+4)(x^2 -4x + 16) = x^3 + 4^3[/tex]

Thus, it is sum of cubes.

Thus, only Option D: [tex](x+4)(x^2 -4x + 16)[/tex] is expressible as sum or product of cubes (here it is expressible as sum of cubes [tex]x^3[/tex] and [tex]4^3[/tex].
