Answer:
2x-4+14=26 add -4+14 this will give you +10
2x+10=26 subtract 10 on both side this will give you 16
2x=16 divide by 2 on both side this will give you 8
x=8
Step-by-step explanation:
Answer:
1x10⁻¹m
Step-by-step explanation:
y = 3x10⁸/x
x is wavelength
y is frequency
what is the wavelength if frequency is 3 x10⁹= y
y = 3x10⁸/x
3 x10⁹ = 3 x10⁸/x
make x the subject of formula
3 x10⁹x = 3 x10⁸
divide both sides by 3 x10⁹
x = 3 x10⁸/3 x10⁹
Adopting law of indices
xᵃ/xᵇ = xᵃ⁻ᵇ
3¹⁻¹x10⁸⁻⁹ = 3⁰x10⁻¹ = 1x10⁻¹m
