Answer:

14x + x^2

------------------

9x^2

Step-by-step explanation:

2x /x^2 + (x-4)/ 9x

Cancel the common factor of x in the first term

2 /x + (x-4)/ 9x

We need a common denominator of 9x

2 /x *9/9 + (x-4)/ 9x

18/9x + (x-4)/9x

Add the numerators

18+x-4

--------------

9x

14+x

----------

9x

Multiply the top and bottom by x to get it to match one of the answers

14x + x^2

------------------

9x^2

While painting, Sam notices that 1/2 cup of paint covers 1/3 of a sign. What is the amount of paint needed to cover the entire s

Verdich [7]

To answer, determine the amount of paint that is needed in order to cover the whole of the sign. If we use the ratio and proportion and letting x be the unknown amount. The equation would be,
1/2 / 1/3 = x / 1
The value of x from the equation is equal to 1.5. Thus, the answer is letter D. 3/2 cups.

Multiplication in GF(24 ): Compute A(x)B(x) mod P(x) in GF(24 ) using the irreducible polynomial P(x) = x 4 + x + 1, where A(x)

tankabanditka [31]

Answer:

Step-by-step explanation:

hello,

i advice you check the question again if it is GF( $2^{4}$ ) or GF(24). i believe the question should rather be in this form;

multiplication in GF( $2^{4}$ ): Compute A(x)B(x) mod P(x) = $x^{4}$ + $x$ +1, where A(x)= $x^{2}$ +1, and B(x)= $x^{3} + x+1$ .

i will solve the above question and i believe with this you will be able to solve any related problem.

A(x)B(x)= $(x^{2} +1) (x^{3}+x+1) mod (x^{4}+x+1 ) = (x^{5} +x^{3}+x^{2} ) + (x^{3}+x+1 ) mod (x^{4} + x+1 )$

= $x^{5}+2x^{3} +x^{2} + x + 1 mod(x^{4}+x+1 )$

= $2x^{2} +1$

please note that the division by the modulus above we used

$\frac{x^{5}+2x^{3}+x^{2} +1 }{x^{4}+x+1}= x+\frac{2x^{3} +1}{x^{4}+x+1}$

The equilateral triangle and the rectangle have the same perimeters. Find the value of x.

castortr0y [4]

We can't answer the question, you haven't given us the information, we need to know what the x is here, or if they gave you a value.

Plzzzz help me on this questions fast <br><br>This is Trigonometry

Sladkaya [172]

Answer:

x ≈ 20.42, y ≈ 11.71

Step-by-step explanation:

Using the cosine ratio on the right triangle on the right, that is

cos20° = $\frac{adjacent}{hypotenuse}$ = $\frac{11}{y}$

Multiply both sides by y

y × cos20° = 11 ( divide both sides by cos20° )

y = $\frac{11}{cos20}$ ≈ 11.71

Using the sine ratio on the right triangle on the left, that is

sin35° = $\frac{opposite}{hypotenuse}$ = $\frac{y}{x}$ = $\frac{11.71}{x}$

Multiply both sides by x

x × sin35° = 11.71 ( divide both sides by sin35° )

x = $\frac{11.71}{sin35}$ ≈ 20.42
