Mrs. singh bought 9 folders & 9 notebooks. the cost of each folder was $2.50. each notebook cost $4. write two equivalent expressions & then find the total cost.

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

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
