The answer should be the first one, 2. Do you need and explanation?
4x+y/2y-x

Start by replacing all of the variables. 
4(2)+4/2(4)-2

Now work multiply. 
8+4/8-2

Now add. 
12/6

That is your fraction. But you must simplify it. 

Its simplifies to 2.

(4(2)+4)/(2(4)-2)

for p(x)= 192 + 21x^3 + 54x^2 - 3x^4 - 264x, use synthetic substitution to evaluate p(1), p(-2), and p(8)
RSB [31]

The value of p(1), p(-2), and p(8) is 0, 744 and 0 respectively

<h3>What is polynomial function?</h3>

Given the function p(x)= 192 + 21x^3 + 54x^2 - 3x^4 - 264x

We are to get the following parameters:

p(1)= 192 + 21(1)^3 + 54(1)^2 - 3(1)^4 - 264(1)\\p(1)=192+21+54-3-264\\p(1)=0

For p(-2)

p(-2)= 192 + 21(-2)^3 + 54(-2)^2 - 3(-2)^4 - 264(-2)\\p(-2)=192-168+216-24+528\\p(-2)=744

For p(8)

p(8)=192 + 21(8)^3 + 54(8)^2 - 3(8)^4 - 264(8)\\p(8)=192+10,752+3,456-12,288-2,112\\p(-2)=0

Hence the value of p(1), p(-2), and p(8) is 0, 744 and 0 respectively

What is the area of the polygon shown below? (in the image). A. 322 mm^2 B. 364 mm^2 C. 520 mm^2 D. 584 mm^2 Show all work pleas
Oksanka [162]

Answer:

A. 322 mm^2

Step-by-step explanation:

The area of the rectangle is 14 times 20

14 x 20 = 280

The area of the rectangle is 1/2 times 14 times 6

1/2(14)(6)=42

Finally add 280 and 42 and the answer is 322
