Answer:
and 
Step-by-step explanation:
The number of people is
and the number of hours they are present in the space is
.
Per person entry cost is $8.
Per hour cost of rent is $40.
They plan to earn a minimum of $600.
Donations by all the people entering the space is 
Total cost of renting the space is
which will be subtracted from the total amount of donations.
The inequality that represents the situation is
and
.
<h2>
d ≈ 19.1 cm</h2>
<em>Using the formulas</em>
<em>C = 2πr</em>
<em>d = 2r</em>
<em>Solving for 'd' (diameter)</em>
<em>d = C</em>
<em>π = 60</em>
<em>π ≈ 19.09859cm</em>

Step 1: Find the value of one variable in terms of the other.

Step 2: Substitute the value you just found for this variable in the other equation.

Step 3: Use your new value for the second variable to find the first.

Now that we know the values for a and b we can find the value of 4a+b.
The product of 2.7 and 1.5 is 4.05.
Answer:
<em>B. (U+V)(U-V)</em>
Step-by-step explanation:
<u>Factoring</u>
The given expression is:

It should be noted that both terms are perfect squares:


Since it's a difference of squares, we need to use the following pattern to factor the required expression:

Thus, the answer is
B. (U+V)(U-V)
