V = (-7,-4)
8v would be 8 times both numbers
8v = (8*-7, 8*-4)
8v = (-56, -36)
magnitude = square root( -56^2 + -36^2)
= sqrt(3136 + 1296)
= sqrt(4432 )
= 4 sqrt(277)
Answer:

Answer:
- 1
Step-by-step explanation:
2x + 3 = x - 4
2x - x = - 4 + 3
x = - 1
The solution to the above equation is - 1.
Answer:
360 = x+123+ 90
x = 147
Step-by-step explanation:
The three angles form a circle which is 360 degrees
360 = x+123+ 90
Subtract 123 and 90 from each side
360 -123 - 90 = x
147 = x
