Answer:
x = 10000
Step-by-step explanation:
Using the rule of logarithms
x = n ⇔ x = 
Given
log x = 4 ( noting that log x has base 10 ), then
x =
= 10000
First find 10%
so 17.64/2
= 8.82
then move decimal over one
so $88.2
is the bill
Value of expression
is
.
<u>Step-by-step explanation:</u>
Here we need to evaluate expression : (3xy/3x^2-12)*(x^2+3x+2/xy+y) or ,

Let's simplify this
⇒ 
Factorizing the terms we get:
⇒
{
}
⇒ 
⇒ 
Cancelling similar terms we get:
⇒ 
Therefore , Value of expression
is
.
Answer:
If you plot these points you will see that the base is 6 (distance from E to F, count the squares).
The height will be 6 ( distance from line EF to D, again count the squares).
Using the Area formula you get A = 1/2 (6) (6) = 18
