Question

Please Help with 31 and 32. I am really confused. Will Select Brainliest Answer.

Answer 1

Answer: C, D

Step-by-step explanation:

31 - use the Pythagorean theorem to find the distance

$a^{2} +b^{2} =c^{2}$

a = 45

b = 28

plug in values

$45^{2} +28^{2} =c^{2} = 2809$

c = 53

answer choice C

32 - non linear functions are functions that aren't straight. if a function has anything besides a constant or an x variable to the power of 1, it is not linear

A - this is linear because -18 is a constant

B - this is linear because it only contains constants and an x variable to the power of 1

C - this is linear because it only contains an x variable to the power of 1

D - this is not linear because the x variable is on the bottom of the fraction, so x is to a power of -1

answer choice D
