Answer: 11r² + 8 ==> C

Step-by-step explanation:

P=Sum of all sides

P=4r² - 1 + r² + 3 + r² + 4 + 5r² + 2

P=4r² + r² + r² + 5r² - 1 + 3 + 4 + 2

P=5r² + 6r² + 2 + 6

P=11r² + 8 ==> C

The number of drama members who are seventh graders is 14.

This is a question of percentages.

Percentage

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.

Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given that:-

Total number of members in the drama club = 40

Percentage of members in the drama club of seventh grade = 35 %

We have to find the number of drama members who are seventh graders.

Number of drama members who are seventh graders = (35/100)*40 = 14

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

He will need 14 boxes which can store can store 8 tins of coffee and 6 boxes that can store 12 tins of coffee.

let us assume:

Number of 8- tin boxes= x

Number of 12- tin boxes= y

we are given the condition that total number of boxes are 20, so-

x+y=20

⇒ x= 20-y

We are also given the condition that he has 184 tins of coffee, so-

8x+12y= 184

⇒ 8(20-y) + 12y = 184

⇒ 160 -8y +12y = 184

⇒ 4y= 24

⇒ y=6

⇒ x=20 -y

⇒ x= 20 - 6

The least integer of the four consecutive even integers is 42

From the question, we are to determine the least integer.

Let the least integer be x

From the given information,

"the sum of four consecutive even integers is 180"

Then,

We can write that

x + (x + 2) + (x + 4) + (x + 6) = 180

x + x + 2 + x + 4 + x + 6 = 180

4x +  12 = 180

4x = 180 - 12

4x = 168

x = 168/4

x = 42

Hence, the least integer is 42

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.)

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

∴ 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

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

       In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.

The meaning of inequality

       A social discrepancy is one example of a characteristic that is unequal or uneven. b: unequal opportunity or distribution.

     A disparity in size, quantity, quality, social standing, or another aspect is what is meant by the term "inequality." When you have ten of something and someone else has none, that is an instance of inequality.

A number = n 12

multiplied by a number = n+12

which is 32 less than the number = 3n-32

n+12 =3n-32

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
