Answer:

6 and 10

Step-by-step explanation:

xy=60

2(x+y)=32

x+y=16

y=16-x

Substitute y into area equation

x(16-x)=60

16x-x^2=60

x^2-16x+60=0

(x-10)(x-6)=0

x=10, 6

y=6, 10

Which expression shows the result of applying the distributive property to 3(15x−17) ?

You just multiply 3 by both 15x and -17. None of these choices are correct. The only correct application would be A.
