Answer:
Step-by-step explanation:
8a^12
----------
b^6
^ means to the power of, problem is that i have a hard time adding the actual symbol.
so when you see ^ when you answer you would have to put it like this:
12
8a
--------
6
b
We have
.
First let us factor the 2 to obtain,

We can now see clearly that the expression inside the parentheses is a difference of two squares.
We now write the 4 as 2². So that we obtain the expression,

Recall that

Hence our expression becomes,

Therefore, when factored completely,

Answer:
2.2 m/s
Step-by-step explanation:
Step one
Given data
An earthquake wave travels through 55 km
hence distance = 55 km
time taken = 25 seconds
<u>Required</u>
<u>the expression relating t and d</u>
Step two:
we know that velocity is
Speed= distance/time
speed= 55/25
Speed= 2.2 m/s
The perimeter would be:
6+6+10+10
12+20
perimeter= 32
HOPE THIS HELPS YOU! ^_^
