Area = (16 x 8) - (6 x 4 ) = 128 - 24 = 104 ft^2
I know one way could be:
(3 × (-6)) + (5 × (-6)) = -18 + (-30) = -48
The other way i dont know
Answer:
The system is dependent:
x=-3t-7
y=-5t-15
z=t
Step-by-step explanation:
I chose to use a matrix to solve this system of equations. Once put into matrix form, you need to row reduce the system into its simplest form (Row Reduced Echelon form). Doing this, we find that the system is dependent on the z variable. And following usual procedures, we let z equal some other letter; which is t in this case. Then we isolate each variable to get the answer.
