Answer:n=-2 or n=4
Step-by-step explanation:
Q is not inversible if det(Q)=0

There is no rectangle but the formula is

1: <span>Commutative Property
2: </span><span>Distributive Property
3: </span><span>Associative Property
I think that that is the right order. :D</span>
the length is given and i got the width as 8 so you just add up all the sides and i got 40
hello i see that no one has answered your question yet well im here to help:)
(1,-19),(-2,-7)
so here one way you can find the slope
i usually always use this to help me to keep it in order
------------------
(X1,Y1)(X2,Y2)
X2-X1
Y2-Y1
use this and your garanteed to get the right answer everytime
------------------
X = -2 – 1 = -3
Y = -7 – -19 = 12
once you do that you divide if possible
12/-3
which gives you -4
so your answer is -4
its really not hard you just got to get use to it
hope it help you:)
