Answer 1

Verified answer

Diketahui :

X = -4 , Y = -11 , z = 2

Ditanya :

a. X² + y - z
b. 2x - 2y + z
c. 4x - y² + 2z

Jawab :
a. X² + y - z =
-4² + (-11) - 2 =
16 + (-11) - 2 =
5 - 2 =
3.

b. 2x - 2y + z =
2(-4) - 2(-11) + 2 =
-8 + 22 + 2 =
14 + 2 =
16.

c. 4x - y² + 2z =
4(-4) - (-11)² + 2(2) =
4(-4) + 11² - 2(2) =
-16 + 121 - 4 =
105 - 4 =
101.
