Add (3x4−2x3+4x−2) and (3x3−2x2−x+4). question 2 options:

a.6x7−4x5+3x+2

b.3x4+x3−2x2+3x+2

c.3x4+5x3+5x+6

d.6x4+x3−2x2+5x+2

B. 3x4 + x3 - 2x2 + 3x + 2

Step-by-step explanation:

3x4 - 2x3 + 4x - 2 + 3x3 - 2x2 - x + 4 add the like terms (the ones with same power)

3x4 (there's no other term with 4th power so we leave this one as it is)

-2x3 + 3x3 = x3

-2x2 (this one as well will be as it is)

4x - x = 3x

-2 + 4 = 2

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
