EXPLANATION
The given vector is v = −14.5i + 2.5 j.
The magnitude of this vector is
![|v| = \sqrt{ {( - 14.5)}^{2} + {2.5}^{2} }](https://tex.z-dn.net/?f=%20%7Cv%7C%20%20%3D%20%20%5Csqrt%7B%20%7B%28%20-%2014.5%29%7D%5E%7B2%7D%20%20%2B%20%20%7B2.5%7D%5E%7B2%7D%20%7D%20)

Answer:
x = -3
Step-by-step explanation:
4x - 1 = -13
add 1 to each side
4x = -12
x = -3
Obtuse because it only takes one obtuse angle to make an obtuse triangle

Answer:
6a + 1
Step-by-step explanation:
First, you need to multiply everything in the brackets by 3L
(7 + 2a) x 3 =
7 * 3 = 21
2a * 3 = 6a
21 + 6a
Now you can subtract the 20 from this:
6a + 21 - 20
Simplified down:
6a + 1
