The lengths of two sides of a triangle are shown below: side 1: 8x2 − 5x − 2 side 2: 7x − x2 + 3 the perimeter of the triangle is 4x3 − 3x2 + 2x − 6. part a: what is the total length of the two sides, 1 and 2, of the triangle? (4 points) part b: what is the length of the third side of the triangle? (4 points) part c: do the answers for part a and part b show that the polynomials are closed under addition and subtraction? justify your answer. (2 points)

my acc plz

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

w'x is 0.

hope it
