Answer:
2a²+3a-2
Step-by-step explanation:
(3a-2a²-1)-(-2a²-2a²+1)
3a-2a²-1+2a²+2a²-1
2a²+3a-2
Since 1 + 1 6= 0, this relation is not reflexive. Since
x + y = y + x, it follows that x + y = 0 if and only if y + x = 0,
so the relation is symmetric. Since (1, −1) and (−1, 1) are both in R,
the relation is not antisymmetric. The relation is not transitive; for
example, (1, −1) ∈ R and (−1, 1) ∈ R, but (1, 1) 6∈ R.

it can be simplified to 1
The speed is the distance covered by an object at a particular time. The speed of the helicopter is equal to 10 kilometer/minute.
<h3>What is speed?</h3>
The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Given the helicopter travels 30 kilometers in 3 minute. Therefore, the speed of the helicopter is equal to,
Speed = 30 kilometer/ 3minutes = 10 kilometer/minute.
Hence, the speed of the helicopter is equal to 10 kilometer/minute.
