If f(x) = x2 + 4x - 12, find f(2).

Answers

Answer 1

Answer:

-3

Step-by-step explanation:

Please write this as  f(x) = x^2 + 4x - 12.  "x^2" represents "the square of x."

f(2) is the value of this function when x = 2:

f(2) =  f(2) = (2)^2 + 4(2) - 12  =  9 - 12 = -3

Solve for w: -4u-w = u+6w

Answers

Answer:

Step-by-step explanation:

Solve for w:

-w - 4 u = 6 w + u

Hint: | Isolate w to the left-hand side.

Subtract 6 w - 4 u from both sides:

-7 w = 5 u

Hint: | Solve for w.

Divide both sides by -7:

Item 4 The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of x. An equation is =540. The solution is x= .

Answers

Let's set the sum of the angle measures equal to 540 degrees.

139 + 3x + 5x - 10 + 10x - 9 + 3x = 540

Let's combine like terms.

21x + 120 = 540

Subtract 120 from both sides.

21x = 420

Divide both sides by 21

Answers

Answer:

64° = ∠KPL116° = ∠JPL

Step-by-step explanation:

The sum of the measures of a linear pair of angles is 180°.

  (2x+24) +(4x+36) = 180

  6x = 120 . . . . . . subtract 60, collect terms

  x = 20

  (2(20) +24)° = 64° = ∠KPL

HELP Plssss..... The m

Answers

Answer:

Step-by-step explanation:

Hey there!!!

According to the question,

Angle P is three less than twice less of an angle Q.

Then, let angle Q be x then angle P is 2x-3.

Now, it has also given that they are supplementary angle.

We know that the sum of supplementary angle is 180°.

Therefore, x+ 2x - 3°=180°.

Or, 3x = 180°-3°

Or, x = 177°/3

Therefore the measure of angle Q is 59° and P is 2×59°-3°= 121°.

2m - n =8 Solve for n

Answers

Answer:

[tex] \boxed{\sf n = 2m - 8} [/tex]

Step-by-step explanation:

Solve for n:

⇒2m - n = 8

Subtract 2 m from both sides:

⇒2m - 2m - n = 8 - 2m

2m - 2m = 0:

⇒-n = 8 - 2 m

Multiply both sides by -1:

⇒-n × (-1) = (8 - 2m) × (-1)

⇒n = 2m - 8

The required value of n is equal to n = 2m - 8.

An expression is given in the question ; i.e., 2m - n = 8.

We have to find the value of the 'n' .

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.

As per the question ;

The given expression is 2m - n = 8.

Let's solve it to get the value of n.

The value of n can be find out , if we bring n to the left side of equal sign and 8 to the right of equal sign.

So ,

2m - n = 8 can be written as ;

2m = 8 + n

or

n = 2m - 8

Thus , the required value of n is equal to n = 2m - 8.
