Answer:
Not necessarily
Step-by-step explanation:
Lets take v1 = (1,0,0), v2 = (1,1,0) and v3 = (0,1,0). Neither of the vectors are a multiple of the other, however they dont generate R³ because for example the vector (0,0,1) is not a linear combination of v1, v2 and v3.
Not that, despite not being a multiple of v1 or v3, v2 is a linear combination of v1 and v3, because it is the sum of both of them. Therefore, the three vectors are linearly dependent and they cant generate a 3 dimensional vector subspace.

Answer:
1440
Step-by-step explanation:
you multiply the 40 with the 36, 40x36=1440 because there are 36 groups of 40.
N/D =(x²+4x+4)/(x² - 4)
N= x²+4x+4 = (x+2)²
D = x²-4 =(x-2)(x+2)
N/D = (x+2)²/(x-2)(x+2); simplify by (x+2)
N/D = (x+2)/(x-2)
Domain of x ={x∈R≠3} ; in short x =( -2) should be excluded
