Can each vector in set of real numbers rℝsuperscript 44 be written as a linear combination of the columns of the matrix a? select the correct choice below and fill in the answer box to complete your choice.
a. no, because the reduced row echelon form of a is
b. yes, because the reduced row echelon form of a is

a) t'(-3, 6) and v'(0, 3)  

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

answer: idk

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
