Answer:
(x, y) = (-2, -1) or (2, 1)
Step-by-step explanation:
Substitute for x in the first equation:
(2y)^2 +3(2y)y = 10
10y^2 = 10
y^2 = 1
y = ±1
x = 2y = ±2
Solutions are (x, y) = (-2, -1) or (2, 1).
The length of the pool table is 4 and the width of the table is 8.
W=4
L=8
W times L=32 or 4 times 8=32
225 (since the fraction is over 180° (because 5Π/4 > Π we know that the answer must be bigger than 180° (because 180° = Π (radians)
and its less than 270° because 270° = 3Π/2 or 6π/4
