Answer 1

1) 20

2) -10

Explanation:

1) 2x + 3y² =

2(4) + 3(-2)² =

8 +3(4)=

8 + 12 =

20

2) -5(x + y) =

-5(4 + -2) =

-5(2) =

-10

Answer 2

we just need to put the values of x,y,z to

x = 4

y = -2

z = 7

1) 2x + 3
`y^(2)`

2(4) + 3(
`-2^(2)`)

8 + 3 (4)

8 + 12

= 20

2) -5(x+y)

-5 (4 + (-2))

-5 (4 -2)

-5 (2)

= -10
