Answer:
$306
Step-by-step explanation:
First you make it into fractions. 1/300 = 2/100
The 2 in the fraction represents the tax rate over 100
The 300 represents the microscope price.
Now multiply the 300 and 2 and 1 and 100
300 x 2 & 1 x 100
600 & 100
Now divide these two
Now you have 6
The 6 is the tax
So now add 300 + 6
$306
Since 4x=28,
x = 28/4 = 7
sub. x = 7 into the eqn,
29-5x = 29-5(7) = 29-35 = -6
1.5 x 3 = 4.5
1.5 + 3 = 4.5
so the answer is 1.5
Answer: fg
and
Domain: All real number. All real number or 
Explanation:
fg means product of two given function f(x) and g(x)
where,
and 
Now, we have to find fg
So, fg=
Substitute f(x) and f(x)

Using distributive property simplify above expression and we get,

We can see it is cubic polynomial. So, domain of cubic polynomial is all real number.
Domain: All real number or 
Answer:
6t - 3
Step-by-step explanation:
9t - 3t + 2
Combine like terms: 9t - 3t = 6t
so
9t - 3t + 2
= 6t - 3
