Answer:

  3, 4

Step-by-step explanation:

The expanded form of the given product is found using the distributive property. An equivalent form can be found using the commutative property of multiplication.

__

  7(2 -3n) = 7(2) +7(-3n) = 14 -21n . . . . . . . matches 3

Swapping the factors gives ...

  7(2 -3n) = (2 -3n)·7 . . . . . . . . . . matches 4

__

About the other choices

1. The value is not the same as 14 -21n. It appears to have been the result of (more or less) adding 7 to the coefficients inside parentheses.

2. It is a common mistake to eliminate parentheses after applying the outside factor to the first term only. That seems to be what happened here. The distributive property says you apply the factor to all the terms inside parentheses.

5. The sum of terms (2 -3n) has been incorrectly replaced by the product of terms (2)(-3n).

3/4 x 960 = 720

Answer:

88 m^2

Step-by-step explanation:

We can split the parallelogram into three shapes. 1 square and 2 triangles.

To find the area of a square, multiply one side by another side that does not face it. To find the area of a triangle, divide the base by half OR multiply the base by 0.5, and then multiply by the height.

Since these shapes are all pieces of the parallelogram, add together their total areas to get the area of the parallelogram.

Square: 7 x 8

Triangle: 0.5 x 4 x 8 or 4/2 x 8

(7 x 8) + 2 x (0.5 x 4 x 8)

56 + 2 x (2 x 8)

56 + 2 x 16

56 + 32

56 + 32 = 88 m^2

Answer:

f(x) = 4x + 6

Step-by-step explanation:

Using f(x) = 4x + 6

lets find some answers

lets take x as (-2)

f(-2) = 4(-2) + 6

f(-2) = -8 + 6

= -2

Also, take x as (-1)

f(-1) = 4(-1) + 6

f(-1) = -4 + 6

Answer:

$0.70 per ounce

Step-by-step explanation:

Concepts + Application

The unit price of an object, in this case, is the total amount of money spent divided by how many ounces there are. We're given the total amount of money as $4.20 and the number of ounces as 6. Thus, we just divide 4.20 by 6.

Answer:

[tex]\begin{matrix}8&2&7\\ 4&&1\\ 5&3&9\end{matrix}[/tex]

Step-by-step explanation:

[tex]\begin{matrix}a&e&b\\ f&&g\\ c&h&d\end{matrix}[/tex]

From the table,we can extract these equations:

a + e + b = a + c + f = b + g + d = c + h + d

a + e + b = a + c + f ⇒ e + b = c + f

b + g + d = c + h + d ⇒ b + g = c + h

[tex]\begin{Bmatrix}e+b=c+f\\ b+g=c+h\end{Bmatrix} \Longrightarrow g-e=h-f\Longrightarrow g+f=h+e[/tex]

2 + 3 = 4 + 1 then let’s consider :

e = 2 ; h = 3 ; f = 4 ; g = 1 ,which satisfies g + f = h + e

The table becomes:

[tex]\begin{matrix}a&2&b\\ 4&&1\\ c&3&d\end{matrix}[/tex]

From the equation b + e = c + f we get b + 2 = c + 4 then b = c + 2

If we consider c = 5 ⇒ b = c + 2 = 5 + 2 = 7

Then the table becomes

[tex]\begin{matrix}a&2&7\\ 4&&1\\ 5&3&d\end{matrix}[/tex]

Then a + 9 = d + 8 ⇒ d = a + 1

If we consider a = 8 ⇒ d = 9

[tex]\begin{matrix}8&2&7\\ 4&&1\\ 5&3&9\end{matrix}[/tex]

Answer: The answer is [tex]16[/tex], You need to reduce the expression, if possible, by canceling the common factors. Then its lateral area of 12 inches and the radius of 3/4 inches would be 16.

Therefore your answer would be [tex]16[/tex].

Based on the concrete of the lateral area and the content of the question, the right answer is 18π

The lateral area is the term that is used to describe the surface of an object as all of the sides of the object, excluding its base and top. Generally, the term lateral area is different from the surface area, which is the lateral surface area together with the areas of the base and top.

Hence, in this case, to calculate the lateral area of the paint roller, find the circumference of the roller and multiply it by its length.

The circumference of a circle can be found using the formula: C = 2πr where r is the radius.

Given that the roller has a radius of 3/4 inch let's substitute this value into the formula to find the circumference:

C = 2π(3/4)

C = 6π/4

C = 3π/2

Now we have the circumference of the roller.

To find the lateral area we multiply the circumference by the length of the roller which is 12 inches:

Lateral Area = Circumference x Length

Lateral Area = 3π/2 x 12

Lateral Area = 36π/2

Lateral Area = 18π

Therefore, in this case, it is concluded that the lateral area of the paint roller is 18π square inches.

Given: (1 + 5i)(3 - 8i)

To find: Multiplication and simplification

Solution:

i=[tex]\sqrt{-1}[/tex],

Now, we simply open the brackets as follows:

(1 + 5i)(3 - 8i)

1(3 - 8i) + 5i (3 - 8i)

3 - 8i + 15i - 40[tex]i^{2}[/tex]

3 + 7i - 40[tex]i^{2}[/tex] - (i)

[tex]i^{2}[/tex] = i * i

[tex]i^{2}[/tex] = [tex]\sqrt{-1}[/tex] * [tex]\sqrt{-1}[/tex]

[tex]i^{2}[/tex] = -1

Associative property

Multiplication properties are different statements that are always true. These statements help prove that different operations can be performed on equations and still remain equal.

Associative Property

The associative property states that (a x b) x c = a x (b x c). This means that in any equation where only multiplication is present, the parentheses can be moved and the equation remains equal.

Other Examples

The associative property is always true; this means that we can create other examples.

Let's take the expression 4 x (2 x 9). As the property states, we can move the parentheses and create the new expression (4 x 2) x 9. Now we can set these expressions equal to each other.

Due to the property we know that this equation must be true.

We can prove this property by working out each side of the equation. If we multiple both sides out we are left with 72 = 72. Since this is true the equation above must also be true.

Answer:

- 95/18

Step-by-step explanation:

1st you have to convert the mixed number to an improper fraction so 2 ×6 = 12 +1 = 13 and that together equals 13/6 same goes for the next take away the parentheses 13/6 - 8/3 - 4 7/9

then you have to do the same thing with the 1st fraction convert it 4 × 9 = 36 + 7 = 43 that equals together 43/9

lastly you have to calculate the difference 13/6 - 8/3 - 43/9 and that equals negative 95/18

by the way the 95 isnt a negative the fraction itself is
