Hey there!

z^2 - 2z + 15

= 15^2 - 2(15) + 15

= 225 - 30 + 15

= 195 + 15

= 210

Therefore, your answer is: 210

Good luck on your assignment and enjoy your day!

Solve the system of equation below x+y+z=2 x-y+5z=6

mamaluj [8]

X + y + z = 2
x - y + 5z = 6

cancelando +y com -y:

x + z = 2*(-5)
x + 5z = 6

-5x -5z = -10
...x +5z = 6
---------------------
-4x = -4 *(-1)
4x = 4
x = 4/4
x = 1

x + z = 2
1 + z = 2
z = 2 - 1
z = 1

x + y + z = 2
1 + y + 1 = 2
2 + y = 2
y = 2 - 2
y = 0

S: {x, y, z} = {1, 0, 1}
