6x^2 - 24x + 4x - 16

6x^2 - 20x - 16

Answer:

(3) 6x^2 - 20x - 16.

Step-by-step explanation:

(3x + 2)(2x – 8)

= 3x*2x + 3x * -8 + 2*2x + 2*-8

= 6x^2 - 24x + 4x - 16

= 6x^2 - 20x - 16.

Answer:

x = -3

Step-by-step explanation:

Answer:

-8, -5, -2, 1, 4

Step-by-step explanation:

The 2x+x on the left side add to 3x

So we have the equation become 3x+8 = 3x-2

Subtract 3x from both sides to get 8 = -2, but that statement is false.

No matter what we replace x with, the original equation will be false.

Answer:

Since we're dealing with absolute value we'll have two answers.

a= c/x-b/x

a= -c/x-b/x

Step-by-step explanation:

Since we can't combine any values inside the absolute value signs we get rid of the absolute value signs.

Now we have: ax+b=c

since we're trying to get a by itself, we subtract the b to get ax= c-b

Now we divide the x and since we can't directly put it with a single value on the right side, we have to put it with both the c and b. Now we have a=c/x-b/x.

For the second answer, you first put a negative with the c. ax+b= -c

Now you solve exactly the same way you did above.

Hope this helps! :)

Answer:

1/10

Step-by-step explanation:

First you've got to find common denominators. The common denominator would be 10 since 10 is divisible by 5 and 10. That means you've got the change the denominator of -4/5. Multiply both the numerator and denominator by 2 to grt -8/10.

Then all you have to do is:

Answer:

8 / √89

Step-by-step explanation:

1. cot (x) = 5/8

2. 8√89 / 89

3. simplify

4. 8 / √89

Value of sin(x) is equals to (8√89) / (89), 0 < x < 90.

" Trigonometric functions are mathematical functions which relates angles and sides of a right angle triangle ,  where 0 < x < 90°."

Formula used

In right angled triangle ABC , ∠B = 90° , ∠C = x°

cot (x )= ( Base ) / ( Opposite side)

sin ( x) = ( Opposite side ) / ( Base )

Pythagoras theorem

(Hypotenuse)² = (Base)² + (Opposite side)²

(AC)² = (AB)² + (BC)²

According to the question,

Given

cot (x) =5 / 8 , 0< x< 90

Therefore, by comparing the given values of trigonometric function with the formula we have,

Base = 5

Opposite side  = 8

Substitute the value in the Pythagoras theorem we get,

    (Hypotenuse)² = 5² + 8²

⇒ (Hypotenuse)² = 25 + 64

⇒  Hypotenuse   = √89                  

Therefore,

sin(x) =  8 / √89

        = 8√89 / 89 ( rationalize √89)

Hence, value of sin(x) is equals to (8√89) / (89), 0 < x < 90.

Answer:

Step-by-step explanation:

Current drawing measurement is 40cm by 80cm using the scale 1cm:22.5cm. This scale means that the original dimension of the court has been reduced by 22.5 for every 1cm. To get the original dimension, we will multiply the given dimension by 22.5cm each as shown.

For 40cm length

Original length = 40 * 22.5

Original length = 900 cm

Convert to metres:

100cm = 1m

900cm = x

cross multiply:

100x = 900*1

x = 900/100

x = 9m

Hence 900cm = 9m

For the 80cm width:

Original width = 80 * 22.5

Original width = 1800 cm

Convert to metres:

100cm = 1m

1800cm = x

cross multiply:

100x = 1800*1

x = 1800/100

x = 18m

Hence 1800cm = 9m

Hence the length and the width of the actual court in metres is 9m by 18m

Answer:

2s√2 square tiles will be needed

Step-by-step explanation:

The first thing we need to do here is to calculate the perimeter of the pool.

Perimeter of square = 4L = 4 * s = 4s foot

Now, let’s calculate the side length of a 2 foot square tile

That would simply be √2 foot

So the number of square tiles needed to tile the border of the pool will be;

4s/√2 = (4 * s * √2)/2

= 2s √2 square tiles

The total number of 2-foot square tiles does it take to tile the border of the pool is [tex]2s\sqrt{2}[/tex] and this can be determined by using the formula of the perimeter of the square.

Given :

A square pool has a side length of s feet.

The following steps can be used in order to determine the total number of 2-foot square tiles does it take to tile the border of the pool:

Step 1 - The formula of the perimeter of square can be used in order to determine the total number of 2-foot square tiles does it take to tile the border of the pool.

Step 2 - The formula of the perimeter is given below:

P = 4L = 4s feet

where L is the length of the side of the square pool.

Step 3 - Now, the side length of the square tile is given below:

[tex]\rm a^2=2[/tex]

[tex]a = \sqrt{2}[/tex]

Step 4 - Now, the total number of 2-foot square tiles does it take to tile the border of the pool is:

[tex]=\dfrac{4s\sqrt{2} }{2}[/tex]

[tex]=2s\sqrt{2}[/tex]
