16 is the answer to this question.
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:
pretty sure it's B, its just really hard to see
Step-by-step explanation:
Answer:
$426
Step-by-step explanation:
Step one:
given data
He bought a video game system for $299
2 games at $49 apiece= 2*49= $98
total cost = 299+98=$397
tax= 7.33%
=7.33/100*397
=0.0733*397
=29.1001
total cost = 29.1001+397
=$426
Answer: -3x + 4, (2,-2)
Step-by-step explanation:
First, you want to get y alone on one side.
3x + y = 4
-4 -4 subtract 4 to get it on the left side.
-y -y subtract y to get it alone on the right side.
Your'e left with 3x - 4 = -y divide the whole equation by -1 do get a pos y
You then have y = -3x + 4. That's the first part of your answer.
To get the second part plug in (-3x + 4) into the y of the first equation, this is the substitution part.
-2x + 5(-3x+4) =-14 distribute the 5... -2x - 15x +20 = -14
add your like terms ( x and x) -17x + 20 = -14
Isolate your x by subtracting the 20, both sides -20 -20
-17x = -34 divide both side by 17 you get x = 2 (---- this is your first coordinate in the pair in your answer. To get the y do the same but solve for y instead of x.
