How many terms are in the polynomial?

x^2 – 121

A. 2
B. 3
C. 4
D. 5

Answer:

9$

Step-by-step explanation:

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

x = 20

Answer:

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

  (4(20) +36)° = 116° = ∠JPL

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.

Step-by-step explanation:

Corinne do 4 pages homework in one hour.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

Corinne take 3 hours to do 12 pages of homework.

Since, We have;

Corinne take 3 hours to do 12 pages of homework.

Hence, In 1 hour, Number of pages = 12 / 3

Answer: 21

Step-by-step explanation:

Answer:

x = 1/2

Step-by-step explanation:

Answer:

x = 0.5

Step-by-step explanation:

2(4x+2)=4x-12(x-1)   (by PEDMAS, we deal with the parentheses first by using the distributive property)

4x(2)+2(2)=4x+ x(-12) -1 (-12)

8x + 4 = 4x - 12x +12  (simplyfy each side)

8x + 4 = - 8x +12   (add 8x to both sides)

8x + 4 + 8x = 12

16x + 4 = 12    (subtract 4 from both sides)

16x = 12 - 4

16x = 8  (divide both sides by 16)

x = 8/16

x = 0.5

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°.

transportation fee= $20

Step-by-step explanation:

Giving the following information:

A canoe rental service charges a transportation fee and $8 an hour to rent a canoe. Mary and Joe rented a canoe for 6 hours, and the total cost was $68.

To calculate the transportation fee, first, we need to calculate the total rent cost for 6 hours.

Rent cost= 6*8= $48

Now, the transportation fee:

transportation fee= 68 - 48

transportation fee= $20

Step-by-step explanation:

Write the original inequality.     6t + 5 > 23

Subtract 5 from each side to undo addition.     6t > 18

Divide each side by 6 to undo multiplication.     t > 3
