Answer:n=-2 or n=4
Step-by-step explanation:
Q is not inversible if det(Q)=0
Answer:
when P(x,y) is reflected in y=x line then
P(x,y) = P(y,x)
A(2, -1)= A(-1, 2)
B(-2, -1) = B(-1, -2)
C(2, 1)= C(1, 2)
D(1,2)= D(2,1)
Step-by-step explanation:
15. 16 yards. Add side a (2 yds.) and b (6 yds.), divide by 2 and then multiply by the height (4 yds.)
16. I believe it would be 48 m. find the area of each rectangle and then add it. (6x2)+(12x3) -> 12+36= 48 square meters.

You need to look at the x values when you calculate that.
There is a line which goes from -2 to 0. Another line at 0 to 4 and the last line is 7 to infinity.
You can combine the first two and get B) (-2, 4] and [7, infinity)
