Add the following polynomials: (−x^3 + 26x^2 − 7x − 13) + (6x^4 − x^3 +8x + 27)6x4  −2x3  +  26x2  −15x  +  14−6x4  +  26x2  +  x  +  146x4  +26x2  −x  −  146x4  −2x3  +  26x2  +x  +  14

Add:  (−x^3 + 26x^2 − 7x − 13) + (6x^4 − x^3 +8x + 27)

You may find it easier to write these one above the other:

             (−x^3 + 26x^2 − 7x − 13)
+ (6x^4 − x^3               +8x + 27)

 6x^4    -2x^3  + 26x^2   +x   + 14   (answer)

Please note:  You should use " ^ " to indicate exponentation.
6x4 −2x3 + 26x2 +x + 14     NO
6x4 −2x^3 + 26x^2 +x + 14    YES

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
