12
The drawing will help
Lines p and q are parrallel.
Step-by-step explanation:
Lines are 180 degrees. We can use that to find out the other angles.
180 - 140 = 40
180 - 40 = 140
12x²y² + 2xy - 2
Work below:
(3xy - 1) (4xy + 2)
Apply FOIL.
= 3xy * 4xy + 3xy * 2 + ( -1 ) * 4xy + ( -1 ) * 2
= 3 * 4xxyy + 3 * 2xy - 1 * 4xy - 1 * 2
= 12x²y² + 2xy - 2
your answer.
x=25
x = 25x1
x = 25
