The quotient of 20 and 3 more than x is 4. Find x.

Answer:

h(x) = 6x² - 10x - 4

Step-by-step explanation:

f(x)g(x) = (2x - 4)(3x + 1)

Each term in the second factor is multiplied by each term in the first factor

2x(3x + 1) - 4(3x + 1) ← distribute both parenthesis

= 6x² + 2x - 12x - 4 ← collect like terms

= 6x² - 10x - 4

To find h(x), which is the product of f(x) and g(x), one must perform a binomial multiplication. The resulting function after simplification is h(x) = 6x² - 10x - 4.

The student is asking for the product of two functions, f(x) and g(x), defined as F(x)=2x-4 and G(x)=3x+1 respectively. To find the new function h(x), which is the result of multiplying f(x) and g(x) together, we use the following process:

h(x) = f(x) × g(x)

This translates into h(x) = (2x - 4)(3x + 1). We need to perform a binomial multiplication (also known as FOIL - First, Outside, Inside, Last) to combine these two expressions.

Applying binomial multiplication, we get:

Combining these terms, we get the final expression for h(x):

h(x) = 6x² + 2x - 12x - 4

Simplifying further:

h(x) = 6x² - 10x - 4

Slope intercept form is [tex]y=mx+b \to y=-3x+4[/tex]

Answer:

y=-3x+4

Step-by-step explanation:

Slope-intercept form is y=mx+b

where m is the slope and b is the y-intercept.

m=-3 because -3 is the slope.

b=4 because 4 is the y-intercept.

Let's plug that into y=mx+b giving us y=-3x+4.

bearing in mind that a diagonal line from the center of a square will give us an isosceles triangle, Check the picture below.

Answer:

The area of this polygon is 98.1 yd²

Step-by-step explanation:

Check the image below.

The diagonal line from the corner of a square to the center of this one will shape an isosceles triangle.

The Pythagoras theorem give us the following formula:

A² + A² = H²

Both "A" are the sides and H is the hypotenuse, seeing the figure, the diagonal coincide with the hypotenuse and the measure is 7 yd.

A² + A² = 72  

2A² = 49

A²= 49/2

A²= 24. 5

A=√24.5

A= 4.95 yd

Knowing that the diagonal ends up in the center of the square, we assume that the side of the triangle (“A” side) is the half of the side of the square, then this last one is 2A. Bearing in mind that square have all of the sides with the same measure, the four sides have a 2A size.

2A = 2(4.95) =9.9 yd

Each side of the square measures 9.9 yd

The area of a square is  

Side²= (2A)2²

(9.9)²= 98.1 yd²

The area of this polygon is 98.1 yd²

The answer is 3x^2+7x+2

Step-by-step explanation:

Multiply each term of the second bracket with the first bracket.

We can write:

(x+2)(3x+1)= 3x(x+2)+1(x+2)

By multiplying the terms we get:

=3x^2+6x+x+2

Now simplify by combining like terms:

=3x^2+7x+2

Thus the answer is 3x^2+7x+2....

Answer:

3x² + 7x + 2

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x(3x + 1) + 2(3x + 1) ← distribute both parenthesis

= 3x² + x + 6x + 2 ← collect like terms

= 3x² + 7x + 2

Answer:

DH and HF correspond.

Step-by-step explanation:

The order matters in a congruence statement.

You are given Figure GHF=Figure EHD.

I say the order matters in a congruence statement because it tells you the parts that correspond.

Angles G and E correspond because they are both first.

Angles H and H correspond because they are both second.

Angles F and D correspond because they are both third.

Answer:0.035

Step-by-step explanation:

I used a calculator and put in 15 / 4 and got 0.035

Charlie should divide the 15 cents into four bags with 1 cent, 2 cents, 4 cents, and 7 cents respectively. Using combinations of these bags, he can pay any amount between 1 cent and 15 cents without opening them.

The question asks us to figure out how Charlie can divide 15 cents among four small bags so he can use these bags to pay any amount between 1 cent and 15 cents without opening them.

To solve this, we need to think about the binary representation of numbers, because each bag can either be used or not used in each transaction, similar to how a binary '1' or '0' can represent 'on' or 'off'.

Therefore, he should put the amounts that correspond to the powers of 2 in three of the bags: 1 cent, 2 cents, and 4 cents, and in the last bag, we put the sum of these three, which is 7 cents.

This way, he can make any amount up to 15 cents:

Then, in order to simplify it, we need to rewrite it in radical form, where the index of the root will be 3 and the radicand will be -62.

one thing to bear in mind is that calculators have two modes, Degree mode and Radian mode, if your calculator is in Radian mode and you plug in tan(39), it thinks "tangent of 39 radians" and so it gives that, bearing in mind that 1 radian is about 57°.

Natasha could have 9 red apples and 4 green apples, or 10 red apples and 3 green apples.

To determine the number of red and green apples Natasha could have, we need to consider the given information. Natasha has a total of 13 apples, and she has more red apples than green apples.

Let's assume that Natasha has r red apples and g green apples. We know that r + g = 13, since she has a total of 13 apples.

Given that she has more red apples than green apples, we can say that r > g.

Now, we need to find the possible values of r and g that satisfy these conditions. We can use trial and error to find the values that work:

Based on our analysis, Natasha could have either 9 red apples and 4 green apples, or 10 red apples and 3 green apples.

Answer:

The volume is 36 inches cubed.

Step-by-step explanation:

The volume of a rectangular prism is W*L*H.

You are given the H=3i, W=2 in, and L=6 in.

So now we plug into our formula for the volume of a rectangular prism which will result in 2*6*3=12*3=36.

The volume is 36 inches cubed.

Answer: [tex]36\ in^3[/tex]

Step-by-step explanation:

The volume of a rectangular prism can be calculated with this formula:

[tex]V=lwh[/tex]

Where "l" is the lenght, "w" is the width and "h" is the height.

In this case we know that this rectangular solid is 3 inches high, 6 inches long and 2 inches wide. Then:

[tex]h=3\ in\\l=6\ in\\w=2\ in[/tex]

Then, substituting these values into the formula, we get that its volume is:

[tex]V=(6\ in)(2\ in)(3\ in)\\\\V=36\ in^3[/tex]
