Answer:
It takes 30 minutes
Step By Step:
The rate of Glenn in finishing a job would be equivalent to:
Rate (G) = 1
job / 20 minutes
While the rate of Veronika is:
Rate (V) = 1
job / x---> x is the unknown
Where 1 job for Glenn means completely cleaning his room while 1 job for Veronika means pulling out everything. Therefore the equation to use would be:
1 / 20 – 1 /
x = 1 / 60
The rate of
Veronika is subtracted from the rate of Glenn since Veronika is slowing Glenn
down. Solving for x:
Multiply both
sides by 60 x
(1 / 20 – 1 /
x = 1 / 60) * 60 x
3 x – 60 = x
2 x = 60
x = 30
Therefore it
takes 30 minutes for Veronika to pull everything out.

How to determine the degree of an expression?</h3>
The degree is just the largest exponent of the variable in an expression.
First, we have:
a) √3xyz - 5
The largest exponent is on the term √3*xyz is 3 (because we add the 3 exponents 1 of x, y, and z) so this expression has a degree of 3.
b) y² - 3y⁵ -y + 2y³ - 4
Here the largest exponent is on the second term, so we can see that the degree is 5.
c) -10³
Here we don't have a variable, so this is a constant, which means that the degree is zero, because we could write:
-10³*x⁰
Where we use the fact that x⁰ = 1
