Answer:

x = 1/2, See Explanation Below

Explanation:

When you solve the equation, you have to take out the 6 first. The mistake is that you Marisol subtracted from 3 directly instead of factoring the x and the 3 out. Below is what you are supposed to do in order to get the right solution.

Step-by-step for Equation:

6(x+3) = 21

6x + 18 = 21

6x = 21 - 18

6x = 3

x = 3/6

x = 1/2

I hope this helps! If you are kind enough, please give me the brainliest answer. It is greatly appreciated if so. Thank You!

Answer:

-9 • (x + 2) • (x - 1)2

Step-by-step explanation:

(-3x-6)(3x2-6x+3)  

Final result :

 -9 • (x + 2) • (x - 1)2

Changes made to your input should not affect the solution:

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (-3x - 6) • ((3x2 -  6x) +  3)

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  -3x - 6  =   -3 • (x + 2)  

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  (3x2 - 6x + 3)  =   3 • (x2 - 2x + 1)  

Trying to factor by splitting the middle term

4.2     Factoring  x2 - 2x + 1  

The first term is,  x2  its coefficient is  1 .

The middle term is,  -2x  its coefficient is  -2 .

The last term, "the constant", is  +1  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 1 = 1  

Step-2 : Find two factors of  1  whose sum equals the coefficient of the middle term, which is   -2 .

     -1    +    -1    =    -2    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -1  and  -1  

                    x2 - 1x - 1x - 1

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-1)

             Add up the last 2 terms, pulling out common factors :

                    1 • (x-1)

Step-5 : Add up the four terms of step 4 :

                   (x-1)  •  (x-1)

            Which is the desired factorization

Multiplying Exponential Expressions :

4.3    Multiply  (x-1)  by  (x-1)  

The rule says : To multiply exponential expressions which have the same base, add up their exponents.

In our case, the common base is  (x-1)  and the exponents are :

         1 , as  (x-1)  is the same number as  (x-1)1  

and   1 , as  (x-1)  is the same number as  (x-1)1  

The product is therefore,  (x-1)(1+1) = (x-1)2  

Final result :

 -9 • (x + 2) • (x - 1)2

The perimeter of the isosceles triangle is C) 32 units.

Step-by-step explanation:

Step 1; First, we plot the three ends of the triangle. Assume the bottom left is A, the bottom right is B and the top end is C. The coordinates are;

A = (-6, -2), B = (6, -2) and = C (0, 6). A triangle's perimeter is the sum of its three side lengths. So we need to determine the side lengths of the given sides.

Step 2; To find the distance between A (-6, -2) and B (6, -2), we use the formula

Distance = √ (x2 - x1)² + (y2 - y1)².

Distance between (-6, -2) and (6, -2) where (-6, -2) is (x1, y1) and (6, -2) is        (x2, y2).

Distance = √ (6 - (-6))² + (2 - (-2))² = √ 12² + 0² = √12² = 12 units.

Step 3; To find the distance between C (0, 6) and B (6, -2), we use the formula

Distance = √ (x2 - x1)² + (y2 - y1)².

Distance between (0, 6) and (6, -2) where (0, 6) is (x1, y1) and (6, -2) is         (x2, y2).

Distance = √ (6 - 0)² + (-2 - 6)² = √ 6² + 8² = √36 + 64 =√100 = 10 units.

Step 4; To find the distance between C (0, 6) and A (-6, -2), we use the formula

Distance = √ (x2 - x1)² + (y2 - y1)².

Distance between (0, 6) and (-6, -2) where (0, 6) is (x1, y1) and (-6, -2) is        (x2, y2).

Distance = √ (-6 - 0)² + (-2 - 6)² = √ 6² + 8² = √36 + 64 =√100 = 10 units.

Step 5; The perimeter of the triangle = 12 + 10 + 10 = 32 units, which is option C.

Answer:

(a) Li and K belongs to the same group.

(b) Mg has the tendency to lose two electrons.

(c) C prefers sharing of electrons to complete its octet.

(d) K is the most metallic element.

(e) S forms acidic oxide.

(f) Al belongs to group 13.

_______________________

(a) Li and K belongs to the same group. (Group 1)

(b) Mg has the tendency to lose two electrons because it has 2 ions in it's outermost shell

(c) C prefers sharing of electrons to complete its octet because it has 6 ions in it's outermost shell need 2 ions to complete octet

(d) K is the most metallic element.

(e) S forms acidic oxide.

(f) Al belongs to group 13.

Answer:

Step-by-step explanation:

⇒15x-20=5y

⇒(15x-20)/5=y

⇒3x

The rate of change of the function is 3

To find the rate of change of the function 15x - 5y = 20, we need to solve for y in terms of x and then determine the coefficient of x, which represents the rate of change.

Let's solve the equation for y:

15x - 5y = 20

Subtract 15x from both sides:

-5y = -15x + 20

Divide both sides by -5:

y = (15/5)x - 4

Simplifying the equation:

y = 3x - 4

Now we can observe that the coefficient of x is 3. Therefore, the rate of change of the function is 3. This means that for every unit increase in x, the corresponding y-value increases by 3.

Answer:

s = 5

Step-by-step explanation:

2m + 4s = 16

Step 1:  Plug in -2 for m

2(-2) + 4s = 16

-4 + 4s = 16

Step 2:  Solve for s

-4 + 4s + 4 = 16 + 4

4s / 4 = 20 / 4

s = 5

Answer: s = 5

Answer:

s= 5

Step-by-step explanation:

s= 5

m= - 2

2m + 4s= 16

Replace the m with the value it is in brackets. Remember brackets mean to multiply.

2(-2) + 4s= 16

-4 + 4s= 16

Carry over the -4 and make s the subject.

4s= 16 - - 4

4s= 16 + 4

4s= 20

s= 20/4

s= 5

Therefore s= 5

To check if the answer was correct, replace the s and m with the value it is in brackets. s= 5; m= 2

2(-2) + 4(5)= 16

-4 + 20 = 16

Therefore s= 5 and the answer is correct!

Answer:

10% Decrease

Step-by-step explanation:

Let the number is 100.

Now, if we increase the number by 20%, the new number will be -

100 + (100 × 20%) = 100 + 20 = 120

The new number is 120.

Again, if we decrease the new number by 25%, the number will be -

120 - (120 × 25%) = 120 - 30 = 90

The new number is 90.

The change will be decreased by = (100 - 90) = 10

Percentage change = (10 ÷ 100) × 100 = 10%

Answer:

$5.99

Step-by-step explanation:

In this problem, Doug paid the following amount for the dinner:

[tex]p=\$39.95[/tex]

He also left a 15% tip.

Here we want to calculate what is the amount correspondant to the tip.

In order to find this value, we have to calculate the 15% of the value of the dinner, therefore we want to find

the 15% of 39.95$

The percentage (15%) can be rewritten as fraction:

[tex]15\% =\frac{15}{100}[/tex]

Therefore, the amount of the tip is

[tex]t=\frac{15}{100}p[/tex]

And substituting p, we find:

[tex]t=\frac{15}{100}(\$39.95)=\$5.99[/tex]

So, the tip is $5.99.

Answer: 5.99

Step-by-step explanation:

Change % to decimal

Then multiply

15% =.15

39.95 x .15 = 5.99

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle = 2(L+W)

Where W is the width of the rectangle  and L is the length of the rectangle

We have been given that Rishi is making a map of a remote village. In this village, each hut has a rectangular base measuring 4 m by 6 m.

Move the points on the grid below to draw the base of one of the huts described above.

As shown in the above figure, just move the top two points down two spaces. Two sides take up four, and the other two take up six. we can find that the length of the hut base is 12 m and the width 8 m.

Therefore, the required dimensions of the hut base will be 8 by 12 m.
