By taking <span>logarithmic of base 10
∴ </span><span>

∴ x log 4 = log 64
∴

note: we don't need to write the base in case of the base =10
∴ The correct choice is
</span><span>x = log base 10 of 64, all over log base 10 of 4</span>
Answer:
out of 250 wala nagka crush sayo hshshs
charot lng
width= 7m
Step-by-step explanation:
Area= L×W
L= (x+8)m
W=8m
105m²= (x+8)m × (x)m
105m²= x² + 8x
-x² - 8x + 105= 0
(x-7) (x+15) = 0
x= 7 x= -15
x=width = 7m
Answer:
10 million out of 10
Step-by-step explanation:
Answer:
boys + girls = 45 -------(1)
There boys 17 more than girls, boys = girls + 17 ----------(2)

girls + 17 + girls = 45
2 x girls + 17 = 45
2 x girls = 45 - 17
2 x girls = 28
girls = 14
substitute in (2): boys = girls + 17 = 14 + 17 = 31
