Answer:
B
Step-by-step explanation:
Log₄(y+2) = 3, transform it into exponent form:
(y+2) = 4³
y+2 = 64
y= 62
B because distributive property goes like this:
a(b+c)
a(b)+a(c)
That's just an example though
Answer:
No
Reasoning:
If something is a perfect cube, it is able to be put under a cube root (
) and will result in an integer (a non-decimal number > 0, basically).
So let's calculate
, and see if the result is an integer.
= 3.634.......
As you can see, the result is not an integer, therefore 48 is not a perfect cube.
A and b can do a piece of work in 12 days. If a alone have to finish the job among b and c so
A and b=12
A (24 days alone without b)
So if b and c 15 days and c 20 days. If a have to do all I would add 24 and 15 and 20 which would be 59 days
