bale kunin mo square roots nila or iradical mo sila to solve
5y-4x ang answer
Step-by-step explanation:
/(25 y^2 - 16x^2)
/(25 y^2) - (16x^2)
(5y)-/(16x^2)
(5y - 4x)
(/)radical sign po yan pc kasi gamit ko
Given: 25y^2= area of the plastic cover
16x^2= area cutted from the plastic cover to cover a card
