Answer:

17, 50, 9

Step-by-step explanation:

Hello

We already know the values of x and y, 5 and 2.

All we have to do to figure out a, b, and c, is to plug in those known values.

a) 3x + y

Let's plug in x and y as 5 and 2

3(5) + 2

15 + 2

17

b) 2x^2

2(5)^2

2(25)

50

c) (x - y)^2

(5 - 2)^2

3^2

9
