Answer:
1. 9 and 11 2. 8 and 9
Step-by-step explanation:
1. we're told x*y=99
two consecutive odd integers will be defined as x and y
then substitute y=x+2
y=x(x+2)=99
y= x^2+2x-99
factor out
x^2-9x-11x-99
x(x-9)-11(x-9)
(x-9)(x-11)
2.
x+y=16
xy=63
y=16-x
x(16-x)=63
16x-x^2=63
63-16x+x^2
x^2-16x+63
x^2-7x-9x+63
(x-7)(x-9)
