Answer:

False. It is half as large.

Step-by-step explanation:

The best way to answer a question like this is to try an example. The easiest case is an equilateral triangle where all 3 sides are equal. So suppose that all sides are 10 units long.

The perimeter (P) is 3s. Let

  • s  = 10 units.
  • Then P = 3*10
  • P = 30

You are instructed to cut all sides in half

  • s = 5
  • p = 3*S
  • p = 3 * 5
  • p = 15

The perimeter is 1/2 as larger as the original, not 1/4. The statement is FALSE.

Does this work with any triangle. Try one that is Scalene (no side equals any other side).

  • s1 = 5
  • s2 = 6
  • s3 = 7
  • P = s1 + s2 + s3
  • P = 5 + 6 + 7
  • P  = 18

Now you cut all three sides in 1/2

  • s1 = 2.5
  • s2 = 3
  • s3 = 3.5
  • P = s1 + s2 + s3
  • P = 2.5 + 3 + 3.5
  • P = 9

9 is 1/2 of 18. The new perimeter is 1/2 the old. The statement is false.

Answer:

The correct option is C.

C) -x + 2

Step-by-step explanation:

In mathematics, the term which is being divided is called a dividend. The term by which the dividend is getting divided is called a divisor. The quotient is the term we get after dividing the dividend by a divisor.

Here in this case, the dividend is written.

-x²    x    x

which in the equation form is written as

-x² + x + x

add the x terms to simplify

-x² + 2x

The divisor is given as x, divide the equation by x:

(-x² + 2x)/x

(-x²/x) + (2x/x)

-x+2

Which is the quotient.

a parallelogram has one angle that measures 55 degrees. what are the measures of the other angles in the parrelogram.
Ugo [173]

a parallelogram has four sides so all its angles add up to make 360

the angle across from the 55 would also be a 55 equaling a 110 degrees angle leaving you with 250 so your other two angles both equal 125

What is the solution to the inequality below? <br> square root x arrow pointing left 9
storchak [24]
If x is less than 81, then we get a solution, but x should also be larger than or equal to zero since radicands must be nonnegative, therefore,  <span>x<81.

A store offers 20% off all items. If x is the original purchase price, which expression represents the final price with the disc
denis23 [38]

Answer:

B & D

Step-by-step explanation:

We use percents in decimal form to multiply it with the price. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.

There are two ways to look at it:

  • For finding the price we pay during a sale, we focus on the percent we pay. If 22% off is the sale, then we spend 78% or 100-22=78. If 20% off is the sale, then we pay 80% or 0.80. Multiply that by x an unknown price and we have 0.8x.
  • We can find the percent off by multiplying the price by the percent conversion. So 20% is 0.20. Then subtract it from the original price to find the leftover that we pay. This is x-0.2x.
