B) negative 21 over 6 degrees Fahrenheit
C) negative 7 over 6 degree Fahrenheit
D) 7 over 6 degree Fahrenheit

A)

× 3

----------

-7 × 3= -21

18 × 3= 54

A IS WRONG!

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
