The value of the equation f ( x ) is

f ( x ) = x³ + x² - 8x - 12

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

f ( x ) = ( x + 2 )²( x -3 )   be equation (1)

Now , on simplifying the equation , we get

f ( x ) = ( x + 2 )²( x -3 )

f ( x ) = ( x² + 4x + 4 ) ( x - 3 )

Now , multiplying each term with ( x - 3 ) , we get

f ( x ) = ( x - 3 ) x² + ( x - 3 ) 4x + ( x - 3 ) 4

f ( x ) = x³ - 3x² + 4x² - 12x + 4x - 12

On simplifying the equation ,we get

f ( x ) = x³ + x² - 8x - 12

Now , the value of the equation f ( x ) = x³ + x² - 8x - 12

On graphing the equation , we get

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

2u - 2/3 = -(3/4)u + 3

Add 2/3 on both sides.

2u = -(3/4)u + 3 + 2/3

Add (3/4)u on both sides.

2u + (3/4)u = 3 + 2/3

(8u + 3u) / 4 = (9 + 2)/3

Answers

The cost of 3 and 1/2 pounds of almond at the same rate is $26.60.

What is a fraction?

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In the illustration given as m/n, it should be noted that m is the numerator and n is the denominator.

Since the price for 7/8 of a pound of almonds is $6.65, the fraction per pound will be done by dividing the amount for a pound by 7/8.

= $6.65 ÷ 7/8

= $7.6

The cost of 3 and 1/2 pounds at the same rate is:

= 3 1/2 × $7.6

= $26.60

In conclusion, the cost is $26.60.

w = L - 4

Substitute: 2L + 2(L-4) = 52

Simplify and solve:

  2L + 2L - 8 = 52

  4L - 8 = 52

  4L = 60

  L = 15

  w = 15-4 = 11

lcd by inspection and division of 1/4, 3/32, 5/48, and 1/8

Answers

Part a: the LCD is measured to be 96 utilizing the inspection method.

Part b: By division of prime numbers: 96.

Explain the term LCD of the Fractions?The LCD of above fractions can be calculated using one of two methods. The inspection method is a name for the first technique. With this approach, the denominator's multiples are acquired, and the result is determined by selecting a common multiple from the pool of available multiples.The division by prime numbers is the name of the second approach. To acquire the LCD, find a prime number which divides the following fractions.

The given number are-

1/4, 3/32, 5/48, and 1/8

Part a:

Find the multiples of the provided fractions' denominators, which are 4, 32, 48, and 8.

4 = 4,8,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88, 92, 96.

32 = 32, 64, 96, 128, 160, 192, 224, 256, 288 ,320.

48 = 48, 96, 144, 192, 240, 288, 336, 384, 432 and 480.

8 = 8, 16, 24, 32, 40, 48, 56, 64, 72, 80

The computation shows that 96, which really is divisible by 4, 32, 48, and 8, is the lowest common multiple.

As a result, the LCD is measured to be 96 utilizing the inspection method.

Part b: By division of prime numbers:

Determine the factors of the given fractions' denominators, 4, 32, 48, and 8.

4 = 2, 2

32 =  2, 2, 2, 2 and 2.

48 = 2, 2, 2, 2 and 3.

8 = 2, 2 and 2.

The generated number, 96, can be divided by the provided fractions' denominators.

As a result, the outcome is 96.

Answers

In the given triangle, the length of side t is 87.7 cm

Calculating the length of a side in a triangle

From the question, we are to determine the length of t.

From the given information,

r = 71 cm

∠T = 48°

∠R = 37°

From the law of sines, we can write that

t / sin T = r / sin R

t / sin 48° = 71/sin 37°

t = (71 × sin 48°)/sin 37°

t = 87.6736

t ≈ 87.7 cm

Find the equation for the line that passes through the point (−2,0), and that is parallel to the line with the equation y=−12x−72

Answers

The linear equation parallel to y = -12x - 72 that passes through (-2, 0) is:

y = -12x - 24

How to find the linear equation?

A general linear equation is written as:

y = m*x + b

Where m is the slope, and b is the y-intercept.

And two lines are parallel only if the lines have the same slope and a different y-intercept.

So, if we want to find a line parallel to:

y = -12x - 72

Then the slope of our line must be -12, then our line is something like:

y = -12x + b

Now we know that the line must pass through (-2, 0), replacing that in our line we get:

0 = -12*-2 + b

0 = 24 + b

-24 = b

The linear equation is:

y = -12x - 24

friend Jane bought a 10.2-pound turkey and a 7.3-pound ham from the same store and paid $24.84.
Find the cost per pound of turkey and the cost per pound of ham.

Answers

Answer:

t = 1.195pounds.

Step-by-step explanation:

The cost per pound of Turkey and Ham are: 1.195pounds and 1.733pounds respectively.

By observing the question, we must notice this is a word problem and can be written mathematically thus;

For Casey:

15.4t + 11.6h = 38.51

For Jane:

10.2t + 7.3h = 24.84

Therefore, to find the cost per pound of Turkey and Ham, the pair of equations need to be solved simultaneously.

Therefore, we can make t the subject of the formula in equation (2) as follows;

t = (24.84 - 7.3h)/10.2

Therefore, we can substitute the value of t into equation (1) to get;

15.4{(24.84 - 7.3h)/10.2} + 11.6h = 38.51

37.51 - 11.023h + 11.6h = 38.51

0.577h = 1

h = 1.733pounds

Therefore, by substituting the value of h into equation 1, we get the value of t to be;

t = 1.195pounds.

The length of a rectangle is 3ft longer than its width.
If the perimeter of the rectangle is,58ft find its length and width.

Answers

The length and width of the rectangle is 16 ft and 13 ft respectively.

What is the dimensions of the rectangle?

The perimeter of a rectangle = 2(length + width)

Perimeter of the rectangle = 58 ftWidth of the rectangle = w ftLength of the rectangle = (w + 3) ft

The perimeter of a rectangle = 2(length + width)

58 = 2{(w + 3) + w}

58 = 2(w + 3 + w)

58 = 2(3 + 2w)

open parenthesis

58 = 6 + 4w

subtract 6 from both sides

58 - 6 = 4w

52 = 4w

divide both sides by 4

w = 52/4

w = 13

Hence,

Width of the rectangle = w ft

= 13 ft

Length of the rectangle = (w + 3) ft

= 13 + 3

= 16 ft

Therefore, the dimensions of the rectangle is given by 16 ft and 13 ft respectively
