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

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)

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

Step-by-step explanation:

(x^4-9+5x^7)+(5x-10+3x^4-2x^2)

x^4+3x^4+5x^7-2x^2+5x-9-10

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

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

the equivalent expression are always the hardest ones but you look at the gcf also
