WILL GIVE BRAINLST
HAVE AN AMAZING DAY :)

x = 2 I think

Step-by-step explanation: 12 x ? = 4 (? + 2) + 20 if you put 2 instead of ? If would be 12 x 2 = 24 is equal to 4(2 + 2) + 20

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

find the magnitude of the trig term  

csc

(

x

)

−

1

by taking the absolute value of the coefficient.

0

the range is  

y

≤

or  

y
