What is the correct simplification of (4x^3 − 3x − 7) + (3x^3 + 5x + 3).

& what is the correct simplification of (5x − 6)(2x^2 − 3x − 6). Thank you :)-7x^3 + 2x - 4 10x^3 - 27x^2 - 12x + 36-4x^3- 3x - 7 3x^3+5x +3 ---------------------- 7x^3 +2x-4 10x^3-15x^2-30-12x^2+

Does g(x + h) = g(x) + (h g'(x) ) as h approach 0 (i get it from (g(x+h)-g(x))/h = g'(x) ).if i am wrong,...

Doesg(x + h) = g(x) + (h g(x) ) as h approach 0 (i get it from (g(x+h)-g(x))/h = g(x) ).if i am wrong, how do i rewrite g(x+h)=?-They arent equal, but they are approximately equal. Since [g(x + h) -

What single discount is equivalent to two successive discounts of 9% and 14%

let initial amount = 100 9% discount = 9 remaining =91 14% discount = 14/100 x 91 =12.74 remaining =91-12.74 =78.26 therefore equivalent discount = 100-78.26 =21.74%

Need help with antiderivatives and integrals

Find f(x) given f(x) = sin(x) + cos(x) f(0) = 3 f(pi/2) = 4 + pi/8 Anyone know how to solve it? Im pretty much stuck. I got that f(x) = -cos(x) + sin(x) + C and f(x) = -sin(x) - cos(x) + C + D but I

Solve for x intercept by completing the square

-x^2-4x+5=0 ? complete the square-- x^2 - 4x + 5 = 0? complete the square - (x^2 + 4x + ___) = - 5 what will complete the square ?did you say + 4 ?I hope so... - (x^2 + 4x + 4) = - 5 - 4 = - 9 -

Graph the equation AND state the Domain & Range: y = |x+2| -1

Email me the answer on a graph, thanks:) alexiak@ymail.com-Since |x+2| = (x+2) for x >= -2 and |x+2| = -(x+2) for x thus draw 2 lines y1, y2 as y1 = (x+2) - 1 or y1 = x + 1 for x>= -2 (only take the p

Area of portion of plane x+3y+2z=6 that lies in first octant.

How should i compute this problem? Thanks-Write this as z = 3 - x/2 - 3y/2, with x,y such that x + 3y = 6 in the first quadrant. So, the surface area equals ∫∫ √[1 + (z_x)^2 + (z_y)^2] dA = ∫(y = 0
