The perimeter:

The length of the longer side:
Answer:
14, 22
Step-by-step explanation:
x+y = 36
2×x - y = 6
=> x = 36 - y
=> 2×(36 - y) - y = 6
72 - 2y - y = 6
-3y = -66
3y = 66
y = 22
=> x = 36 - 22 = 14
Answer:
No
Step-by-step explanation:
Sides AB to DC aren't congruent/parallel
Sides BC to AD aren't congruent/parallel

The additive inverse<span> of a number a is the number that, when added to a, yields zero. This number is also known as the opposite.</span>
small number = x and large number = 2x + 9
x + 2x + 9 = 2(2x + 9 - x)
3x + 9 = 2x + 18
x= 9
2(9) + 9 = 27
Small number = 9 and large number = 27
