7/12 all you need to do is figure out the lowest common denominator and multiply it, then simply add them together.

Which operation between two polynomials will not always result in a polynomial?
Assoli18 [71]
In order to build a polynomial we need one or more terms. A term is a number, variable (denoted by a letter) or any combination of numbers and variables held together by multiplication. The following are examples of terms:

5, 3x, -5ab c^{2},  \frac{2x^{3}y }{5},  x^{6}

Now it might look like one of those involves division but it can be thought of as multiplication by (2/5). When we do this the exponents must be positive.

Polynomials are expressions made up of terms held together by addition and subtraction. Again, the exponents must be positive. Since polynomials are made up of the sum or difference of terms, adding or subtracting polynomials just leads to more polynomials. Here are some examples of Polynomials:

4xy-3 x^{2} +7,  \frac{2x}{5}-3abc-5j

Now let’s consider what happens if we multiply polynomials. As an example we use: (x+5)(2x-y)=2 x^{2} +10x-xy-5y

What you might notice is that multiplication will lead us to multiply terms (but multiplying terms gives us more term,as) and also to add or subtract terms but that just gives more polynomials. Therefore multiplication leads to more polynomials.

Finally, we consider division. Here a simple example will do the trick: 2 is a term and x is a term. Let us divide 2 by x. We get: \frac{\2}{x}=2 x^{-1}  which is not a polynomial because we have a negative exponent. 

Thus, the answer to your question is division. Division of polynomials will not always result in a polynomial.

40 POINTS<br> Can anyone answer question 8 only e ii and iii please
Nutka1998 [239]

Answer:

ii)  c = 4    iii) c = 8

Step-by-step explanation:

A = x axis intercept = 1/2 c

B = y axis intercept = c

ii)  Area of a triangle = 1/2 x base x height

                               4 = 1/2 x (1/2)c x c

                              c² = 16

                                c = 4

iii)  2√5 will be the hypotenuse of a right-angled triangle with base 1/4 c and height 1/2 c

(2√5)² = (1/4 c)² + (1/2 c)²

      20 = 1/16 c² + 1/4 c²

      20 = 5/16 c²

         c² = 64

          c = 8

The distance from Earth to the moon is approximately 1.2 x 10 to the power of 9 feet. The Apollo 11 spacecraft was approximately
Vlada [557]

Answer:

3,333,333 spacecraft

Step-by-step explanation:

To get the number of spacecraft that would fit between earth and moon <em>divide the distance by the length of the spacecraft</em>.

When 1.2\times10^{9} is divided by 360 the quotient will be 3,333,333 and the remainder will be 120.

It means 3,333,333 Apollo 11 spacecraft will fit between earth and moon but still 120 feet will remain and no more spacecraft can completely fit in it.
