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)

step-by-step explanation: yes

idk this answer sorry cant on this one.

step-by-step explanation:

both equations and proportions are better.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
