Question

rq2 + 3qr + r2 for r = 5 and q = 2

Answer 1

Just plug it in like this; (5)(2)+3(2)(5)+5(2)

Answer 2

rq^2 + 3qr + r^2 -- r = 5 and q = 2
now we sub
5(2^2) + 3(2)(5) + 5^2
5(4) + 6(5) + 25
20 + 30 + 25
50 + 25
75

Answer 3

I hope the 2's are powers....like 2^2, instead of just multiplying by 2

Answer 4

They are!
