Answer:

[tex]6 \times 6 \times 6 = 216 \\ = 216[/tex]

Answer:

216 Value

6 times 6 times 6 =216

Answer:

x=-4

Step-by-step explanation:

1. Distribute

3(2x+8)=0

6x+24=0

2. Subtract 24 from both sides.

6x+24=0

6x+24-24=0-24

3. Simplify

6x=-24

4. Divide both sides of the equation by the same term

6x=-24

[tex]\frac{6x}{6}[/tex] = [tex]\frac{-24}{6}[/tex]

5. Simplify

x=-4

And thats the answer.

I hope this helps        :)

Answer:

Step-by-step explanation:

(-2, -3)  (-1, -1)

(-1 + 3)/(-1 + 2)= 2/1 = 2

y + 3 = 2(x + 2)

y + 3= 2x + 4

y = 2x + 1

The simplified expression is: -243v^5

Answer:

1/3 of the pizza remains.

Step-by-step explanation:

Matthew eats 1/3 of 1/2 of the pizza, which is (1/3)*(1/2) = 1/6 of the pizza.  The amount of pizza left is

1/2 - 1/6 = 3/6 - 1/6 = 2/6 = 1/3

1/3 of the pizza remains.

Answer:

12

Step-by-step explanation:

12 - 4 = 8

The square of 8 is 64

Answer:

6

Step-by-step explanation:

(n + 4)^2 = n^2 + 64

n^2 + 8n + 16 = n^2 + 64

8n = 48

n = 6

Answer:

C. 3x+2=4

Step-by-step explanation:

6x+4=8

Subtract 4 from both sides.

6x=4

Divide both sides by 6

x=4/6

Simplify it

x=2/3

3x+2=4

Subtract both sides by 2

3x=2

Divide both sides by 3

x=2/3

Hope this helps

Answer and Step-by-step explanation:

The correct answer choice is answer choice 3. [ 3x + 2 = 4 ]

6x + 4 = 8

6x = 4

x = 2/3

_________________________________________________________

3x + 2 = 4

3x = 2

x = 2/3

Step-by-step explanation:

Angle K is congruent to Angle N (given), Angle H is congruent to itself (reflexive property), and side JH is congruent to side MH (given).

Answer:

A is the answer because...

Step-by-step explanation:

Let's narrow it down, so it is not D because 8/2=4 but 64/4=16, so already they don't share a slope. It is not B because the numbers don't work together like they should, since we are trying to prove proportionality. It is not C because we are not trying to square the numbers but find a similarity between the numbers, the same slope I mean. So that leaves A which has  the slope of 2, test it out now. 0 and 0 are the same, 4/2=2, 8/4=2, 12/6=2. So now you know that A is the correct answer.

Hope you understand! :)

Answer:

27.84 m² , 42.48 m²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Shape A

has b = 9.6 and h = 5.8, then

A = 0.5 × 9.6 × 5.8 = 27.84 m²

Shape B

has b = 11.8 and h = 7.2 , then

A = 0.5 × 11.8 × 7.2 = 42.48 m²

Answer:

Shape A = 55.68

Shape B = 79.2

Step-by-step explanation:

Shape A work : [tex]9.6[/tex] x [tex]5.8[/tex] = 55.68

Shape b work :  11 x 7.2 = 79.2

Answer:

12.5 sq units. Explanation: Area of a triangle with vertices (x1,y1),(x2,y2),(x3,y3) is 12[x1(y2−y3)+x2(y3−y1)+x3(y1−y2)]. Using this formula ...

Step-by-step explanation:

you have to study

The value of the area of circle is,

Area = 15 units²

And, The value of perimeter is,

⇒ 6 + √34 + 5√2 Units

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The triangle with vertices A(4, 3) B(-2, 3) and C(-1, - 2).

Now, We know that;

Area of triangle with vertices (x₁, y₁) (x₂, y₂) and (x₃, y₃) is,

= 1/2 [ x₁ (y₂ - y₃) + x₂ (y₃ - y₁) + x₃(y₁ - y₂) ]

Hence, We get;

The value of the area of circle is,

Area = 1/2 [ 4 (3 + 2) - 2 (- 2 - 3) - 1 (3 - 3) ]

Area = 1/2 [ 20 + 10 ]

Area = 1/2 x 30

Area = 15 units²

We know that;

The distance between two points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

Hence, Lenght of AB is,

AB = √ (- 2 - 4)² + (3 - 3)²

AB = √- 6²

AB = 6

BC = √ (- 2 - 1)² + (3 + 2)²

BC = √9 + 25

BC = √34

CA = √ (- 1 - 4)² + (- 2 - 3)²

CA = √25 + 25

CA = √ 50

CA = 5√2

Thus, The perimeter of triangle is,

⇒ AB + BC + CA

⇒ 6 + √34 + 5√2

Answer:

5^11

Step-by-step explanation:

The simplification form of the given expression 5² · 5⁹ would be  5¹¹ which is the correct answer that would be an option (A).

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

It is a relation of the form y = aˣ  in mathematics, where x is the independent variable

We have to determine the simplification form of the expression 5² · 5⁹.

The given exponential expression below as:

⇒  5² · 5⁹

Apply the multiplication operation, and add the exponents because the same base of the exponential expression,

⇒  5² ⁺⁹

⇒  5¹¹

Therefore, the simplification form of the given expression would be  5¹¹.

Answer:

2.67 x 10^3

Step-by-step explanation

The exponent is equal to how many numbers are after the decimal point. So, since there are 3 numbers after the decimal point, the exponent would be 3. Hope this helps :)

Step-by-step explanation:

perimeter - 16cm

length - 5cm

find breadth,

perimeter of rectangle = l × b

16cm = 5 × b

b = 16/5

b = 3.2 cm

Step-by-step explanation:

Given

perimeter (P) = 16 cm

Length(L) = 5 cm

breadth (b) = ?

We know

P = 2 (L + b)

16 = 2 ( 5 + b)

16 = 10 + 2b

2b = 16 - 10

2b = 6

b = 6 / 2

b = 3 cm
