Are the expressions (x + 7) (x - 3) and (x + 7) equivalent expressions? explain

No

Step-by-step explanation:

(x+7)(x-3) are different from (x+7), since they generate a different result when foiling.

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
