Answer:
Step-by-step explanation:
2) 8=n+3/-2
we cross multiply
n+3=8*(-2)
n+3= -16
n= -16 - 3
n= -19
lets check if we are correct
8=-19+3/-2
8= -16/-2
-16/-2=8
4) 9=x/2+6
we first calculate the fraction
x/2+6
L. c. m is 2
x/2+6/1=4x + 8/2=12x/2
2 times 2=4 plus x = 4x
2 times 1 =2 plus 6= 8
thats how i got 4x + 8/2
back to the question
9=12x/2
cross multiply
12x=9*2
12x=18
x=18/12
we will use 2 to divide it
9/2
3 will divide
3/2
x=3/2
Two answers are n being 0 or 2.

Answer:
x^-13
Step-by-step explanation:
The cofactors of each entry in the first row of the matrix are
Ac_11 = -13
Ac_12 = 44
Ac_13 = 27
We have to determine the cofactors of each entry in the first row of the matrix.
Therefore the cofactors of each entry in the first row of the matrix are
Ac_11 = -13
Ac_12 = 44
Ac_13 = 27.
A set of numbers is arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.
Machines had to find a way to cut themselves off from the truth in order to understand humans. Neo's sole purpose in the Matrix is to prevent machines from evolving into dinosaurs.

Answer:
55.4
Step-by-step explanation:
Think of it as a right angled triangle, the length of the ladder (17ft) is the hypotenuse, the length of the ground (14ft) is the rise, we then use sin to get the angle as the angle of elevation is the angle between the ladder and the ground hence sin^-1 (14/17) and you get your angle.
