Answer 1

Answer:

x=3/4

Step-by-step explanation:

(3x-1)²=25

(3x-1)=√25=5

3x=5-1=4

x=3/4

Answer 2

Answer:

$( 3x - 1) {}^{2} = 25 \\ ( 3x - 1) {}^{2} = 9x {}^{2} - 6x + 1 \\ since. \\ (a - b) {}^{2} = {a}^{2} - 2ab + {b}^{2} \\ therefore \\ 9x {}^{2} - 6x + 1 = 25 \\ 9x {}^{2} - 6x = 25 - 1 \\ (9x {}^{2} - 6x ) \div 3x= 24 \\ 3x - 2 = 24 \\ 3x = 26 \\ x = 8.667$
