Question

Evaluate A2 for A = -3. -9 -6 6 9

Answer 1

Ok so basically it is saying substitue when a equals all of those numbers,so basically I will show you.

a (times) 2 = ?   so substitute one of the numbers for a which would be like this its basically multiplication so, (-3) (times) 2 = -6 so that solves one part do the same with the other numbers and that will give you all the answers like so,

(-9) (times) 2 = -18   (-6) (times) 2 = -12    (6) (times) 2 = 12 and finally the last one is (9) (times) 2 = 18 which are all correct answers.

so basically, your answers are gonna be -6,-18,-12,12,18 which are or should be all correct

Answer 2

Evaluate A² for A = -3.

(-3)² = (-3) * (-3) = 9

Your answer is 9.

If the question is, however, evaluate A2, which is 2A, for A = -3, then the answer is:

2A = 2(-3) = -6.
