Answer:

8x³ - 2x² - 51x - 45

Step-by-step explanation:

Given

(x - 3)(2x + 3)(4x + 5) ← expand second/third factors using FOIL

= (x - 3)(8x² + 22x + 15) ← distribute

= x(8x² + 22x + 15) - 3(8x² + 22x + 15) ← distribute parenthesis

= 8x³ + 22x² + 15x - 24x² - 66x - 45 ← collect like terms

= 8x³ - 2x² - 51x - 45

Answer:

8x^3-2x^2-51x-45

Step-by-step explanation:

(x − 3)(2x + 3)(4x + 5)

(2x^2+3x-6x-9)*(4x+5)

(2x^2-3x-9)*(4x+5)

= 8x^3-2x^2-51x-45

Step-by-step explanation:

2(x+10)=60

x=30-10=20

Answer:

Step-by-step explanation:

In order for us to be able to find our answer, we need to show our work.

-3(x-y=3) → -3x + 3y = -9

                 +2x - 3y = -1

____________________________

                  -1x = -10

                   -1      -1

We need to divide -1 both sides in order for us to be able to find our x-value but there's more to this than just solving for X.

x = 10

x - y = 3

10 - y = 3

-10       -10

_________________

-y = -7

-1     -1

We need to divide -1 both sides in order for us to be able to find our y-value. Please note that each y is equivalent to an invisible 1.

y = 7

As a result, your answer will be B.

Answer:

Independent Events

Step-by-step explanation:

Given

[tex]Green = 3\\ Orange = 2\\ Red = 5[/tex]

Required

Dependent or independent event

The probability of selecting a green jelly remains unchanged before and after selecting the first orange jelly.

Before selecting the orange jelly:

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

After selecting the orange jelly:

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

Because the probabilities remain unchanged, the selection of a green jelly is independent of the selection of the first orange jelly.

Answer:

(3,-2)

Step-by-step explanation:

4x+y=10

y=10-4x

x-y=5

x-(10-4x)=5

x=3

y=10-4x

y=10-4(3)

y=-2

Answer:

5 rentals for $30

Step-by-step explanation: *using y = mx + b*

Info Given:

Video Club A-

$10 (would be your b)

$4 (would be your x)

Video Club B-

$15 (would be your b)

$3 (would be your x)

HOW TO SOLVE:

Video Club A - y = 4x + 10

Video Club B - y = 3x + 15

Set them equal to eachother to solve for x!

4x + 10 = 3x + 15

     - 10         - 10

4x = 3x + 5

-3x -3x

x = 5 rentals

Plug in the x into both or just one equation to find the price!

y = 4x + 10

  = 4(5) + 10

  = 20 + 10

y = $30

Answer:

Step-by-step explanation:

Angle 1 is equal to angle 3 because they are opposite each other so

Angle 1=43 degrees

Angle 1 and angle 2 have a sum of 180 degrees because they are adjacent to each other.

angle 2=180-43=137 degrees.

angle 2 and 4 are opposite each other so they are equal

angle 4=137 degrees.

Answer:

Angle 1 = 43°

Angle 2 = 137°

Angls 4 = 137°

Step-by-step explanation:

To get angle 1, l and m intersect and there are two angles which cause vertical opposite angles. When there are vertical opposite angles, both angles have the same degree. For angle 2, you need to find angle 1 and 3, after that you deduct both angle 1 and 3 from 360° which is the angle of whole figure. 360 - 43 - 43 = 274° for angle 2 and 4, since they're also vertically opposite angles, both 2 and 4 have the same angle. All you need to do to find 2 and 4 is 274 ÷ 2 = 137°.

Answer:

82° ; 50° ; 52° ;domain error ;51° ; domain error

Step-by-step explanation:

Using a calculator :

sin(A) = 0.9903

A = sin^-1(0.9903) = 82.01 = 82°

6.) cos(A) = 0.6428

A = cos^-1(0.6428) = 49.99 = 50°

8.) tan(A) = 1.2851

A = tan^-1(1.2851) = 52.111 = 52°

9.) cos(A) = 1.2608

A = cos^-1(1.2608) = domain error

10.) sin(A) = 0.7777

A = sin^-1(0.777) = 50.98 = 51°

11.) sin(A) = 1.8330

A = sin^-1(1.8330) = domain error

Use Elimination Method....

2x - y = 2

2x - 2 = y

y = 2x - 2 ----------- equation 1

5x + y = -9

Substitute for y

5x + 2x - 2 = -9

7x = -9 + 2

7x = -7

x = -7/7

x = -1

Substitute for x in equation 1

y = 2x - 2

y = 2(-1) - 2

y = -2 - 2

y = -4

Answer:

(- 1, - 4 )

Step-by-step explanation:

Given the 2 equations

2x - y = 2 → (1)

5x + y = - 9 → (2)

Adding the 2 equations term by term will eliminate the y- term, that is

7x + 0 = - 7

7x = - 7 ( divide both sides by 7 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (2)

5(- 1) + y = - 9

- 5 + y = - 9 ( add 5 to both sides )

y = - 4

solution is (- 1, - 4 )

Answer:

2 - 30ft²

3 - 57yd²

Step-by-step explanation:

Hey There!

The first step in solving this problem is finding the formula for area of a trapezoid

[tex]A = \frac{a+b}{2} h[/tex]

a = base 1

b = base 2

h = height

For the first one the dimensions are

a = 6

b = 9

h = 4

now we just plug in the values

[tex]A=\frac{6+9}{2} 4\\6+9=15\\\frac{15}{2}=7.5\\7.5*4=30[/tex]

so the area of the first trapezoid is 30 ft²

For the second one the given dimensions are

a = 8

b = 11

h = 6

now we just plug in the values

[tex]A=\frac{8+11}{2} 6\\8+11=19\\\frac{19}{2} =9.5\\9.5*6=57[/tex]

so the area of the second trapezoid is 57 yd²

Answer:

He would factor out 4(x+5)

Step-by-step explanation:

You can't do much until the 4(x+5) is factored out.

Once it is then it'd be 3x-8=4x+20

Then you subtract 3x on both sides and subtract 20 on both sides.

You'd be left with -28=x
