How many vertices has a closed cone? a. 1 b. 2 c. 3 d. 4

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

the perimeter is increased by a factor of 2

3x + 4y -25 =0 represents the amount of change sianna should recieve

answer:

a=9
