After multiplying, the answer of (4+2√3)(6-3√3) is 15.

1. Divide the radicands by two. Under the radical sign, there is a number called a radicand. 2. Multiple the integers as though they were whole numbers in order to multiply radicands. Keep the product under a single radical sign at all times.

3. Remove any perfect squares from the radicand by factoring. Check to determine whether the radicand is a factor of any perfect squares to do this.

4. Before the radical sign, place the square root of the ideal square. Keep the second element in the radical sign.

5. Square the root of a square. A square root may occasionally need to be multiplied by itself.

(4+2√3)(6-3√3)

⇒ 4 ×6 + 4 × -3√3 + 2√3 × 6 - 2√3 × 3√3

⇒ 24 - 12√3 + 12√3 - 9

The number of books that Mrs. Johnson bought is 8 books.

How many magazines did she buy:

Let x represent the number of books she bought

The first step is to formulate an equation

12x + 16 = 112 dollars

The second step is to transpose

12x=112-16  

12x = 96

The third step is to divide both sides by 12

x=96/12  

x = 8

The inverse for the function f (x) = 1.2 x⁴ will be f ⁻¹ (x) = ⁴√ ( 5 x / 6).

We are given the function:

f (x) = 1.2 x⁴

we need to find the inverse of the function.

First we will write the function in the form of x.

y = 1.2 x⁴

y / 1.2 =  x⁴

x = ⁴√ ( y / 1.2)

x = ⁴√ ( 5 y / 6)

So, the inverse function will be:

f ⁻¹ (x) = ⁴√ ( 5 x / 6)

Therefore, the inverse for the function f (x) = 1.2 x⁴ will be f ⁻¹ (x) = ⁴√ ( 5 x / 6).

Considering the definition of an inequality, all possible values for the length of the sides of the square picture are greater than 3 inches but less than 8.75 inches.

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

The perimeter of a two-dimensional figure is the distance around the figure. That is, the perimeter of a flat geometric figure is called the length of its contour.

The perimeter is the measurement obtained as a result of the sum of the sides of a flat geometric figure.

A square is a flat geometric figure that has four equal sides, so the expression to calculate the perimeter of a square is:

Perimeter= 4× length of the sides

In this case, you know that the perimeter of a square picture frame is to be at most 35 inches but no less than 12 inches.

Being "S" the length of the sides of the square picture, the inequality that expresses the previous relationship is

12 inches< 4×S ≤35 inches

Solving:

12 inches ÷4< S ≤35 inches ÷4

3 inches <S≤ 8.75 inches

Finally, all possible values for the length of the sides of the square picture are greater than 3 inches but less than 8.75 inches.

The area of the square is found as -8 unit².

Distance between two coordinates (x₁, y₁) and (x₂, y₂)  are-

d = √[(x₁ - x₂)² + (y₁ - y₂)²]

Consider two given coordinates;

(x₁, y₁) = H(1,-3) and

(x₂, y₂) = G(3,-1)

Put the values in the given distance formula;

d = √[(1 - 3)² + (-3 + 1)²]

d = √[(-2)² + (-2)²]

On solving,

d = 2√2 unit

Thus, one side of the square is found as 2√2 unit.

The area of the square is given as;

Answer:

[tex] \sf \: m=−1[/tex]

Step-by-step explanation:

5(4m+1)-2m=-13

Step 1: Simplify both sides of the equation.

5(4m+1)−2m=−13

(5)(4m)+(5)(1)+−2m=−13(Distribute)

20m+5+−2m=−13

(20m+−2m)+(5)=−13(Combine Like Terms)

18m+5=−13

18m+5=−13

Step 2: Subtract 5 from both sides.

18m+5−5=−13−5

Increasing: [-7, -2] U [4, ∞]

Decreasing: [-2, 4]

Positive: [-5, 2] U [6, ∞)

Negative: [-7, -5] U [2, 6]

The equation of the line in fully simplified slope-intercept form is y = -x + 3

From the question, we are to write the equation of the line in fully simplified slope-intercept form

The slope-intercept form of the equation of a straight line is given as

y = mx + b

Where m is the slope of the line

and b is the y-intercept

From the graph,

The y-intercept is 3

∴ b = 3

Now, we will determine the slope, m, of the line

Given any two points (x₁, y₁) and (x₂, y₂) on a line, the slope, m, of the line is

m = (y₂ - y₁)/(x₂ - x₁)

Picking the points, (0, 3) and (2, 1)

m = (1 - 3)/(2 - 0)

m = -2/2

m = -1

Putting in the slope, m, and the y-intercept, b into the equation of a line

y = mx + b

We get

y = -1(x) + 3

Simplify

y = -x + 3

Hence, the equation of the line in fully simplified slope-intercept form is y = -x + 3

Answer:

Step-by-step explanation:

For an equation to be parallel the slopes must be the same.  The slope from the equation is 12.

y = mx + b  is the slope-intercept form of a line'

y = 12x + 3.  The m is the slope and that is 12 ion this equation.

We will use the slope (12), the x (0) and the y (0) to write the new equation.  We need to find the y intercept.  We can see from the ordered pair given that the y - intercept would be zero, but here is another way to check.

y = mx + b

0 = 12(0) + b

0 = 0 + b

0 = b

y = 12x + 0

First suppose that √19 + √3 > √5 +√13

On squaring both sides and using the identity [tex](a+b)^2=a^2+b^2+2ab[/tex],

⇒ [tex](\sqrt{19}+\sqrt{3})^2 > (\sqrt{5}+\sqrt{13})^2\\22+2\sqrt{57} > 18+2\sqrt{65} \\[/tex]

Dividing by 2 on both sides,

⇒ [tex]11+\sqrt{57} > 9+\sqrt{65}[/tex]

Subtracting 9 from both sides,

⇒ [tex]2+\sqrt{57} > \sqrt{65}[/tex]

Squaring again, we get,

⇒ [tex]61 +4\sqrt{57} > 65[/tex]

Subtract 61 on both sides,

⇒ [tex]4\sqrt{57} > 4[/tex]

Dividing by 4 on both sides,
