Answer: Zero; 9; -18
Step-by-step explanation:
An additive inverse always adds up to zero. 9 is the opposite of -9, and -18 is the opposite of 18
2x + 2y = 6 . . . . . (1)
x + 3y = -1 . . . . . (2)
(1) x 3 => 6x + 6y = 18 . . . . . (3)
(2) x 2 => 2x + 6y = -2 . . . . . (4)
(3) - (4) => 4x = 20
x = 20/4 = 5
Answer:3.42

Answer:
432 ft²
Step-by-step explanation:
The formula of finding the area of a trapezoid: (base 1 + base 2/ 2) x h
(base 1 + base 2/ 2) x h
= (20 + 28/2) x 18
= 24 x 18
= 432 ft²
