Number 2 is 84.13
number 4 is 56
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)
Answer:
$30, $75, $45
Step-by-step explanation:
We can set up an equation, where x is an unknown value:
2x+5x+3x=150
10x = 150
x=15
Now that we know what x is, we can plug x in to solve for 2x, 5x, and 3x:
2x=2*15=30
5x=5*15=75
3x=3*15=45
Therefore, the answer is $30, $75, $45
The answer is A. I just finished the test.
