Question

I NEED HELP PLZ!!!!!!!!!!

Answer 1

1/25
anything multiplied by 0 is 0
so 1/5 is left
5 square is 25 because 5x5 is 25
keep the numerator
so it 1/25

Answer 2

1/25

Explanation:

Since it only contains 1 unknown, given that r = 0, what you need to do is to substitute r=0 into the expression

= (5(0) + 1/5)^2

= (1/5)^2

=1/25
