if 4 x x4 = 12 24 find x matrices

​

Answer 1

Answer:

Let C be the capacitance of a capacitor discharging through a resistor R. Suppose t₁ is the time taken for the energy stored in the capacitor to reduce to half its initial value and t₂ is the time taken for the charge to reduce to one-fourth its initial value. Then the ratio t₁/t₂ will be

Answer 2

Answer:

Either the photo is incomplete or typed question is incomplete

because when this type of situation comes(in photo) the x = 1 or x = 4
