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)

answer: 12

step-by-step explanation:

because yes

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

add them
