2n - 2

Step-by-step explanation:

rewrite without parentheses, pretend there is a 1 between the minus sign and the open parentheses that has to be distributed:

3n - 1(2 + n)

3n - (1)(2) + (-1)(n)

3n - 2 - n

combine 3n and -n to get 2n

Step-by-step explanation:

Alright, lets get started.

Area is given as 49 square inches.

The formula for area A =  

base is given as x

Height is given as x

Hence area is A

A =  

Multiplying 2 in both sides

Taking square root on both sides

hence the answer is x = 9.9 in   :  Answer

Hope it will help :)

The value of x is 9.9 in.

Solution:

The given image is a triangle.

Base of the triangle = x

Height of the triangle = x

Area of the triangle = 49 sq. in

To find the value of x:

Area of the triangle =  

Substitute the given values in the formula.

Multiply by 2 on both sides, we get

Taking square root on both sides, we get

⇒ x = 9.9 in

Hence the value of x is 9.9 in.

Answer:

7√2

Step-by-step explanation:

From the diagram given;

Hypotenuse = x

Opposite = 7

Angle = 45 degrees

According to SOH CAH TOA identity

Sin theta = opposite/hypotenuse

Sin 45 = 7/x

x = 7/sin45

x = 7/1/√2

x = 7 * √2/1

x = 7√2

Hence the value of x is 7√2

Answer:

7x^2*(x-4)*(x+6)

Step-by-step explanation:

7x^4 + 14x^3 - 168x^2

common factor 7x^2

7x^2*( x^2+2x-24)

now we factor ( x^2+2x-24)

(x-4)*(x+6)

Solution

7x^2*(x-4(*(x+6)

The factorized form 7x²(x-4)(x+6) of the polynomial 7x⁴ + 14x³ - 168x².

What is polynomial ?

The polynomial is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

Given polynomial as:

7x⁴ + 14x³ - 168x²

There is a common factor 7x²

7x²( x² + 2x - 24)

To determine the factor of ( x² + 2x - 24)

⇒ 7x²( x² + 2x - 24)

⇒ 7x²( x² + 6x - 4x -24)

⇒ 7x²[x(x+6) - 4(x+6)]

⇒ 7x²(x-4)(x+6)

Hence, the factorized form 7x²(x-4)(x+6) of the polynomial 7x⁴ + 14x³ - 168x².

Answer:

Part A: 84, 105

Part B: $315

Step-by-step explanation:

Part A:

4 student tickets + 5 adult ticekts = 9 tickets

The ratio of student tickets to adult tickets to total tickets is

4 : 5 : 9

He sold x times more tickets than the numbers on the ratio.

He sold 9x tickets.

9x = 189

x = 21

Student tickets:

4x = 4(21) = 84

He sold 84 student tickets.

Adult tickets:

5x = 5(21) = 105

He sold 105 adult tickets.

Part B:

Student tickets:

He sold 84 student tickets at $5 each.

The amount of money from the sale of student tickets is:

84 * $5 = $420

Adult tickets:

He sold 105 adult tickets at $7 each.

The amount of money from the sale of adult tickets is:

105 * $7 = $735

Difference:

$735 - $420 = $315

84 student tickets, 105 adult tickets were sold by Jin and $315  more money does Jin receive from selling adult tickets than from selling student tickets

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

The ratio of student tickets to adult tickets sold is 4 : 5

4 student tickets + 5 adult ticekts = 189

4x+5x=189

9x = 189

Divide both sides by 9

x = 21

The number of Student tickets:

4x = 4(21) = 84

Jin sold 84 student tickets.

Adult tickets:

5x = 5(21) = 105

Jin sold 105 adult tickets.

Part B:

He sold 84 student tickets at $5 each.

The amount of money from the sale of student tickets is:

84 * $5 = $420

Adult tickets:

He sold 105 adult tickets at $7 each.

The amount of money from the sale of adult tickets is:

105 * $7 = $735

Difference:

$735 - $420 = $315

Hence 84 student tickets, 105 adult tickets were sold by Jin and $315  more money does Jin receive from selling adult tickets than from selling student tickets

Area of the circular sidewalk around flowerbed is 207.24 m² .

Area is the amount of space occupied by a two-dimensional shape. That is, it is a quantity that measures the number of unit squares that cover the surface of a closed figure. Standard area unit is square unit.

Given,

Diameter of flowerbed = 19m

radius = diameter/2 = 19/2 = 9.5 m

Area of flower bed A

= πr²

= 3.14(9.5)²

= 3.14(90.25)

= 283.385 m²

width of the sidewalk = 3m

radius of flower bed with sidewalk = 9.5 + 3 = 12.5m

Area of flower bed with sidewalk A'

= 3.14(12.5)²

= 3.14(156.25)

= 490.625 m²

Area of the sidewalk

= A' - A

= 490.625 - 283.385

= 207.24 m²

Hence, 207.24 m² is area of the circular sidewalk around flowerbed.

Answer:

Step-by-step explanation:

A parallelogram is a shape that has two sets of parallel. There are a number of examples of parallelogram including but not limited to, square, rectangle, rhombus etc

From the question, the answer is, the shape is a rectangle. This is because the question says that the shape has its adjacent angles congruent, this means that they are supplementary(i.e they add up to 180). A rectangle is the one who fits the perfect description

Answer:

perimeter = 18 units

area = 20 square units.

Step-by-step explanation:

We know that a rectangle is defined by two measures, length L, and width W.

Such that the perimeter is given by:

P = 2*(L + W)

and the area is given by:

A = L*W

Here we know that the vertices of or rectangle are:

(-1, 6)

(-1, 2)

(4, 2)

(4, 6)

Here you can see that we have just two different values of x (-1 and 4) and two different values of y (6 and 2)

So we can define the length L as the difference between the two different values of x:

L = 4 - (-1) = 4 + 1 = 5 units

And the width as the difference between the two different values of y:

W = 6 - 2 = 4 units

A graph of the rectangle can be seen below, to see why I choose to define the length and width in this way.

Now that we know the measures of our rectangle, and using the above formulas for perimeter and area, we get:

P = 2*(W + L) = 2*(5 + 4) = 18 units

A = W*L = 5*4 = 20 square units

Answer:

The hypotenuse is sqrt ( 2x^2)

Step-by-step explanation:

Given a right angled triangle, we can find the hypotenuse of a triangle using the Pythagorean theorem which says that c^2 = a^2 + b^2, where a is the length, b is the perpendicular height and c is the hypotenuse. The length of the triangle (l) is x and the height of the triangle is also x. By substituting the values,

c^2 = x^2 + x^2 = 2x^ 2

There are two possible answers to c but the hypotenuse cannot be negative.

Hence,

c = Sqrt (2x^2)

Answer:

∠ BOC = 40°

Step-by-step explanation:

∠ AOC = 90° , then

5x + 2x + 20 = 90

7x + 20 = 90 ( subtract 20 from both sides )

7x = 70 ( divide both sides by 7 )

x = 10

Then

∠ BOC = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°
