The answer is the option C, which is: C. √29
The explanation of this exercise is:
To solve this problem you must apply the proccedure shown below:
1- You have that:
W (-2,8,-3) and X(1,4,-1)
2- Therefore, you can calculate the magnitude as below:
|WX|=√[(1-(-2)]²+(4-8)²+[(-1-(-3)]²)
|WX|=√29
Answer:
You can multiply m-8 by 2.
You can subtract 3 from both sides of the equation.
Step-by-step explanation:
Answer:
(x + 5)(3x + 5)
Step-by-step explanation:
(x - 5)(x + 8) + (x + 5)(2x - 3) ← factor out (x + 5) from each term
= (x + 5)(x + 8 + 2x - 3)
= (x + 5)(3x + 5)
If you would like to solve the system of equations, you can do this using the following steps:
x - 3y = 12 ... x = 12 + 3y
2x + 6y = 60
__________
<span>2x + 6y = 60
</span>2 * (12 + 3y) + 6y = 60
24 + 6y + 6y = 60
12y = 60 - 24
12y = 36
y = 36/12
y = 3
<span>x = 12 + 3y = 12 + 3 * 3 = 12 + 9 = 21
</span>
(x, y) = (21, 3)
The correct result would be <span>(21, 3).</span>
