Add these polynomials and simplify. Enter your response in standers form (x^4-9+5x^7) + ( 5x -10 +3x^4 - 2x^2)
Natali [406]

Answer:

5x^7 + 4x^4 - 2x^2 + 5x - 19

Step-by-step explanation:

Start by copying 5x -10 +3x^4 - 2x^2 here.  Next, add x^4 to +3x^4, -9 to -10, and 5x^7:

5x - 10 +3x^4 - 2x^2

     -  9  +x^4               + 5x^7

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

5x - 19 + 4x^4 - 2x^2 + 5x^7

Now rearrange these terms in descending order by powers of x:

5x^7 + 4x^4 - 2x^2 + 5x - 19   (answer)

DiKsa [7]

Answer:

A = 2200x - 2x^2

Step-by-step explanation:

Let's x be the length of the side that is NOT the same as the side along the river (or in opposite). From the fencing perimeter of 2200ft we can calculate the other side y of the rectangular:

y = 2200 - 2x

The area A of the pen would be the product of the 2 sides

A = xy = x(2200 - 2x) = 2200x - 2x^2
