Use the distributive property to expand the following expression. Then combine the like terms.
-3(-2b + 5a + 7n - 10a + 6n +4a)
(please help me!!)

Answers

Answer 1

Answer:

6b + 3a - 39n

Step-by-step explanation:

Expanding using the distributive property :

-3(-2b + 5a + 7n - 10a + 6n +4a)

Multiply all values in the bracket by - 3

6b -15a - 21n + 30a - 18n - 12a

Collect like terms

6b - 15a + 30a - 12a - 21n - 18n

6b + 3a - 39n

3 ft
3.ft

2 ft

Answers

9514 1404 393

Answer:

  32 ft^2

Step-by-step explanation:

The area can be figured several ways. Here are two of them.

__

Add components

The figure can be divided into two smaller rectangles, (b) and (d) in the attached drawing. The area of each is the product of its dimensions.

  Area b = (4 ft)(3 ft) = 12 ft^2

  Area d = (10 ft)(2 ft) = 20 ft^2

Area of the figure is Area b + Area d = 12 ft^2 + 20 ft^2 = 32 ft^2.

__

Subtract white space

The figure is bounded by an overall rectangle that is 10 ft wide and 5 ft high. The area of that rectangle is

  Area a+b+c+d = (10 ft)(5 ft) = 50 ft^2

The area of whitespace 'a' is ...

  Area a = (3 ft)(3 ft) = 9 ft^2

Area c has the same dimensions, so the same area. The area of the figure is the area of the bounding rectangle less the area of the two corner white spaces (a) and (c).

Area of the figure is ...

  Area a+b+c+d -Area a -Area c = 50 ft^2 -9 ft^2 -9 ft^2 = 32 ft^2.

Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee assuming the same function applies to any numbers of shirts bought how much in dollars would 1 shirt cost before the shipping fee

Answers

Answer:

15 Dollars

Step-by-step explanation:

If you take the shipping price (3 dollars) off you get 15 per shirt

If Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee then one shirt costs $15 before the shipping fee.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given that Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee.

We have to find the cost of one shirt before the shipping fee.

Let x be the cost of one shirt before the shipping fee.

Then, we can set up two equations based on the given information:

2x + shipping fee = 33

3x + shipping fee = 48

We can solve for the shipping fee by subtracting the first equation from the second:

3x + shipping fee - (2x + shipping fee) =48 - 33

x= 48 - 33

x = 15

So one shirt costs $15 before the shipping fee.

Hence,  if Greg paid $33 for 2 shirts and $48 for 3 shirts including a fixed shipping fee then one shirt costs $15 before the shipping fee.

Hope this helps

Answer:

x = 7

Step-by-step explanation:

4(x + 2) = 36

4x + 8 = 36

4x + 8 - 8 = 36 - 8

4x = 28

4x ÷ 4 = 28 ÷ 4

x = 7

Meg is decorating a ballroom ceiling with garland the width of the rectangle ceiling is 42 meters and the diagonal distance from one corner to the opposite corner is 70 metere . How much garland will meg need for the length of the ceiling

Answers

Answer:

[tex]47.3\,m[/tex] of garland is required for the length of the ceiling.

Step-by-step explanation:

Width of a rectangle ceiling [tex](w)=42 \,m[/tex]

Diagonal of a rectangle ceiling [tex](d)=70\,m[/tex]

Let [tex]l[/tex] denotes length of a rectangle ceiling.

The relationship between length, width and diagonal of a rectangle is given as follows:

[tex]d^2=l^2+w^2\\70^2=l^2+42^2\\4900=l^2+1764\\l^2=4900-1764\\l^2=2236\\l=47.3\,m[/tex]

So,

[tex]47.3\,m[/tex] of garland is required for the length of the ceiling.

Answers

The rectangular prism’s volume would need to be calculated.

Volume = length * width * height

Volume = 84 * 5 * 2

Volume = 840

The difference needs to be subtracted

840 - 100 = 740

D) p³ + 2; when p = 3 the number of plants is 29.

Step-by-step explanation:

Illiana cubed (³) the number of original plants, p, in the garden. Then, she added 2 more plants. We will use n for the number of total plants.

So, the equation should be p³ + 2. Substitute our value for p into the equation and solve.

p³ + 2 = n

3³ + 2 = n

27 + 2 = n

29 = n

There are 29 total plants.

The answer, then, is the last option, p³ + 2; when p = 3 the number of plants is 29.

I NEED HELP ASAP

Answers

Answer:

Step-by-step explanation:

Profit, P(x), is the difference between revenue, R(x), and cost, C(x)

R(x) = 2x^4 - 3x^3 + 2x - 1

C(x) = x^4 -x^2 + 2x + 3

Substituting into the equation

P(x) = R(x) - C(x)

= (2x^4 - 3x^3 + 2x - 1) - (x^4 -x^2 + 2x + 3)

= x^4 - 3x^3 + x^2 - 4

The answer is the lower left option.

Answer:

[tex]P(x)=x^4-3x^3+x^2-4[/tex]

(This is the option found in the lower-left corner)

Step-by-step explanation:

When given the following functions,

[tex]R(x)=2x^4-3x^3+2x-1[/tex]

[tex]C(x)=x^4-x^2+2x+3[/tex]

The problem asks one to find ([tex]P(x)[/tex]), moreover, one is given the following information,

[tex](P(x))=(R(x))-(C(x))[/tex]

Substitute,

[tex]P(x)=(2x^4-3x^3+2x-1)-(x^4-x^2+2x+3)[/tex]

Simplify, multiply everything in the second parenthesis by the negative sign outside of it,

[tex]P(x)=2x^4-3x^3+2x-1-x^4+x^2-2x-3[/tex]

Combine like terms, only operations between coefficients of the same variable with the same degree (exponent) can be performed,

[tex]P(x)=x^4-3x^3+x^2-4[/tex]

Matt’s gym charges more to reserve the basketball court.

To determine Matt’s cost of reserving the court, look for the difference between the mostly cost each time the court is reserved another time.

The cost of reserving the court one time is: $52.75.

The cost of reserving the court two times is: $55.50.

$55.50 - $52.75 = $2.75, therefore the cost of reserving the court is $2.75.



However it’s important to check your work to make sure that the cost increases by a constant amount. Check the difference between each time the court is reserved another time.

The cost of reserving the court two times is: $55.50.

The cost of reserving the court three times is: $58.25.

$58.25 - $55.50 = $2.75. The cost of reserving the court for a third time is an additional $2.75.

Finally, The cost of reserving the court three times is: $58.25.

The cost of reserving the count a forth time is $61.

$61 - $58.25 = $2.75, therefore the incremental cost of reserving the cost a forth time is $2.75.

Based on the information, Matt’s gym charges $2.75 every time he wants to reserve a court, whereas Tyrell’s gym only charges him $2.00, therefore Matt’s gym charges more.
