Solve the equation
12E − 4 = 0

Answers

This could get complicated.  Please try to follow my steps carefully:

Begin by writing the equation to be solved:    12E - 4 = 0

Add 4 to each side of the equation:  12E = 4

Divide each side by 12:                      E = 4/12 = 1/3 .

The given quadratic equation can be represented in the form (x-p)^2 = q

by adding 3 to both sides of the equation.

What is a quadratic equation?

The polynomial equation whose highest degree is two is called a quadratic equation. The equation is given by

ax^2 + bx + c = 0

where a\neq 0.

The given quadratic equation is

x^2 - 8x + 13 = 0

Case 1: Subtract 5 from both sides of the equation

i.e.  x^2 - 8x + 13 - 5 = 0 - 5

⇒   x^2 - 8x + 8 = -5

The LHS of the above equation can not be expressed in (x-p)^2 form. Hence, it is not the correct step.

Case 2: Add 3 to both sides of the equation.

i.e. x^2 - 8x + 13 +3 = 0 + 3

⇒  x^2 - 8x + 16 = 3

⇒  x^2 - 2* x * 4 + (4)^2 =3

⇒  (x - 4)^2 = 3

The above equation is expressed in (x-p)^2 = q form where p = 4 and q = 3.

Case 3: Add 5 to both sides of the equation

i.e. x^2 - 8x + 13 + 5 = 0+5

⇒   x^2 - 8x + 18 = 5

The LHS of the above equation can not be expressed in the (x-p)^2. Hence, it is not the correct step.

Case 4: Subtract 3 from both sides of the equation

i.e. x^2 - 8x + 13 - 3 = 0-3

⇒   x^2 - 8x + 10 = -3

The LHS of the above equation can not be expressed in the (x-p)^2. Hence, it is not the correct step.

Hence, "Add 3 to both sides of the equation" is the correct step.

Add 3 to both sides, so you will have

x^2 - 8x + 13 + 3 = 3
x^2 -8x + 16 = 3

And now the left side is a perfect square trinolmial: (x-4)^2.

What is the area of rectangle PQRS?

Answers

The length of PQ = 3 + 4.5 + 2 = 9.5 inches.

The area is Length times width:

4.5 x 9.5 = 42.75 square inches.


The answer is D.

Add 2+4.5+2 and that is 9.5 PQ=9.5

multiply 4.5*9.5

that is 42.75 so the answer is D

A recipe calls for 2/3 of a cup of milk for 11 cookies. How many cups of milk are needed to make 99 cookies?

Answers

Answer:

6 cup of milk

Step-by-step explanation:

From question

         for 11 cookies → (2)/(3) of a cup of milk required

         Now,

                  for 99 cookies

          we multiply both sides by 9.

                        11 × 9 = (2)/(3) × 9

                  for 99 cookies = 6 cup of milk
