85

Step-by-step explanation:

Just plug in 12 for x, 8 for y, and 3 for z.

x+y^2+z^2

12+(8×8)+(3×3)

12+64+9

=85

Plsss help and thank u

Answer:

11/16

Step-by-step explanation:

There are 9 red crayons, 2 blue crayons, and 5 yellow crayons. We can represent this as a ratio of 9:2:5. Now we have to combine the red crayons and blue crayons so it's 11 red and blue crayons: 5 yellow crayons OR 11:5. Then we add those two values to find out the number of crayons there are, and there are 16. So out of 16 times, you will pick up a red or blue crayon 11 times. So this fraction is 11/16 which is already its simplest form.
