What are the possible values of x if (4x – 5)2 = 49? check all that apply. -4/5 -1/2 3 5 7

4 x - 5 = - 7
4 x = - 2
x = -
or 
4 x - 5 = 7
4 x = 12
x = 3
Answer B) and C)

(4x-5)^2 = 49

Extract square root from both sides

4x-5 =(+/-)7

4x = 5 +7 and 4x = 5 -7

4x = 12 and 4x = -2

x = 12/4 and x = -2/4

x= 3 and x =-1/2

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
