The properties of equality used in the equation are subtraction properties and multiplication properties of equality

The complete question is added at the end of the solution

From the complete question, the equation is given as:

(1/3d + 4 = 28)

Start by removing the bracket in the given equation

So, we have

1/3d + 4 = 28

Next, we continue by applying the subtraction properties of equality

This means that we subtract 4 from both sides of the equation.

So, we have:

1/3d + 4 - 4= 28 - 4

Evaluate the difference in the above equation

So, we have

1/3d = 24

Next, we continue by applying the product properties of equality

This means that we multiply both sides of the equation by 3

So, we have:

3 * 1/3d = 24 * 3

Evaluate the products in the above equation

So, we have

d = 72

By looking at the computations above, we can see that we apply the following properties:

The area of the composite figure is 58. 71 square units.

It is important to note that the area of the composite figure is given as;

Area of a rectangle + area of a semi circle

The formula for area of a rectangle is expressed as;

Area = lw

Where;

Now, let's substitute the values, we have;

Area = 6 × 9

Area = 54 square units

The formula for area of a semicircle is expressed as;

Area = πr²/2

Where;

Given diameter = 6, radius = 6/2 = 3

Substitute the value

Area = 3. 14(3)/2

Area = 4. 71 square units

Answer:.

Step-by-step explanation:

The duration of shoot would be 2 hours and Either stylist would cost $282 if the shoot lasted 2 hours.

A fashion photographer needs to hire a stylist to prepare his models.

Let the number of hours stylist take = x

Jayla charges $156 for showing up, plus $63 per hour. So, this can be mathematically written as ,

156 + 63x                                                  equation 1

Sally charges $158 plus $62 per hour.  So, this can be mathematically written as ,

158 + 62x                                                  equation 2

As per the question, the expected duration of his photo shoot, either stylist would cost him the same amount. So we can equate equation 1 and equation 2. On equating equation 1 and equation 2 , we will get

156 + 63x  = 158 + 62x

⇒  x = 2

So, the duration would be 2 hours.

Jayla cost = Sally cost = 156 + 63x  = 156 + (63 × 2) = 282

Either stylist would cost $282 if the shoot lasted 2 hours.

In linear equation, oil required to cover oil all the pieces in one box of big pasta with same thin layer of oil = 1/2 of the oil.

What are a definition and an example of a linear equation?

Let the dimensions of one piece of your favorite kind of pasta  be l, b, h.

Volume of one piece of pasta = l b h

Surface area of one piece of pasta = 2( lb + bh + lh)

Let the no of pasta piece in the box ( favorite  one ) be 'n' = .

Total volume = n × lbh

Total  Surface area = n . 2( lb + bh + lh)

In the bigger size pasta box dimensions of one piece of  of pasta 2l , 2h , 2b .

∴ Volume of one piece of pasta = 2l × 2b  × 2h   = 8lbh

Surface area of one piece of pasta = 2( 4lb × 4bh × 4lh)

                                                         = 2 × 4 ( lb × bh × lh )

Let the no of pasta pieces in the bigger pasta box in m.

Total volume of pasta = m × 8lbh

total surface area = m . 4 × 2 ( lb × bh × lh )

the total volume of pasta is also same in the box.

  mass =  density ×  volume

D × m .8 lbh  =  D × n . lbh

  m = n/8

total surface  area of  pastas in bigger pasta box = m × 4 × 2 ( lb × bh × lh)

                                                                           = n/8 × 4 × 2  ( lb × bh × lh )

                                                              =      n/8 × 1/2 × n× 2  ( lb × bh × lh )

                                                      = 1/2 × surface area (total) of small pasta

The integers in the solution set of 3p − 10 ≥ 7p + 6 are -4 and -5

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

The set is given as

S: {−2, −3, −4, −5}

The inequality expression is given as

3p − 10 ≥ 7p + 6

We start by evaluating the inequality expression

So, we have

3p − 10 ≥ 7p + 6

Subtract 7p from both sides of the inequality expression

So, we have

-4p − 10 ≥ 6

Add 10 to both sides of the inequality expression

So, we have

-4p ≥ 16

Divide both sides of the inequality expression hy -4

So, we have

p ≤ -4

This means that the integers in the solution set are integers that do not exceed -4

These integers are -4 and -5

Hence, the solution is -4 and -5

Answer:

Step-by-step explanation:

The quadratic expression when ( x - 2) ( x - 7 ) is multiplied is x² - 9x + 14.

A polynomial of degree two or a quadratic polynomial that has two as the highest exponent of the variable. A quadratic polynomial will typically have the following form: p(x): ax² + bx + c, a ≠ 0.

A coefficient is a multiplicative factor in a polynomial term, a series term, or an expression; it often has the form of a number but can also take the form of any expression.

When an expression ( x - r )( x - s ) is multiplied, where r and s are integers, we obtain a quadratic polynomial.

Therefore, when ( x - 2 )( x - 7 ) is multiplied we get:

( x - 2 )( x - 7 ) = x( x - 7 ) - 2( x - 7 )

( x - 2 )( x - 7 ) = x² - 7x - 2x + 14

( x - 2 )( x  - 7 ) = x² - 9x + 14

Answer:

Step-by-step explanation:

You want the zeros of f(x) = x³ -5x² -22x -16, given that a factor is x+2.

Using synthetic division (see attachment), we find the quadratic factor to be (x² -7x -8), so we have ...

  f(x) = (x +2)(x² -7x -8)

The quadratic can be factored using our knowledge of the divisors of -8 to give ...

  f(x) = (x +2)(x +1)(x -8)

The zeros of f(x) are the values of x that make these factors zero:

  x = -2, -1, 8 . . . . . zeros of f(x)

__

Additional comment

We know the product of binomial factors is ...

  (x -a)(x +b) = x² -(a-b)x -ab

This means we can factor the quadratic by looking for factors of 8 that have a difference of 7. We know that 8 = 8·1 and that 8-1=7, so the values of 'a' and 'b' we're looking for are a=8, b=1.

The "zero product rule" tells you a product is zero only if one of the factors is zero. That is how we know to look for the zeros of the binomial factors of f(x). For example, x+2=0 ⇒ x=-2 is a zero of f(x). (The remainder of 0 in the synthetic division also tells us f(-2)=0.)
