Given: 
Use Exponent Rule: 
Use Addition Rule: 
Answer:
$6000
Step-by-step explanation:
accumulated amount = A = PI
A = $6900
Let P = x
6900 - I = x
I = (x)(0.05)(3yrs) = 0.15x
6900 - 0.15x = x
Add
6900 = 1.15x
Divide, solve for x
x = 6000
Answer:
(x+11)(x-11)
Step-by-step explanation:
A ^2 - B ^2 =(A+B) (A-B).. (*)
x^2 - 121=
x^2 - 11^2=(*)
(x+11)(x-11)
Answer:
45
Step-by-step explanation:
Answer:
<h2>x = 3.1</h2>
Step-by-step explanation:
<h3>

</h3>
<u>To solve first take logarithm to both sides</u>
That's
<h3>

</h3><h3 /><h3>

</h3>
But
<h3>

</h3>
So we have

<u>Write 1200 as a number with the factor 100</u>
That's
1200 = 100 × 12
So we have
<h3>

</h3>
<u>Using the rules of logarithms</u>
That's
<h3>

</h3>
Rewrite the expression
That's
<h3>

</h3><h3 /><h3>

</h3><h3>

</h3><h3>

</h3><h3 /><h3>

</h3>
x = 3.079
So we have the final answer as
<h3>x = 3.1 to one decimal place</h3>
Hope this helps you
