Evaluate the following expression using the values given. Find 2x2 − 2z4 + y2 − x2 + z4 if x = −4, y = 3, and z = 2.

Explain how you got your answer.

-19

Step-by-step explanation:

2×2-2z4+y2-x2+z4

now we put the value,

4-2(2to the power 4)+(3 to the power 2)-(-4 to the power 2)+(2 to the power 4)

4-2×16+9-16+16

4-32+9

4+9-32

13-32

-19

please check the answer again i am sorry if it's wrong

1,918

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
