[tex]\huge{\underline{\underbrace{\mathcal\color{gold}{Answer}}}}[/tex]
[tex]\tt{3(x-5)+2=29 }[/tex] ⠀
[tex]\tt{3x-15=29-2 }[/tex] ⠀
[tex]\tt{ 3x=27-15 }[/tex] ⠀
[tex]\tt{ 3x=12 }[/tex] ⠀
[tex]\tt{ x=\dfrac{12}{3} }[/tex] ⠀
[tex]\tt{x=4 }[/tex] ⠀
So,
According to the question,
[tex]\tt{ x^2=x×x=4×4=16}[/tex] ⠀
Answer:
[tex]\huge\boxed{\sf x^2 = 16}[/tex]
Step-by-step explanation:
[tex]\sf 3(x+5) +2 = 29\\\\Resolving \ Parenthesis\\\\ 3x + 15 + 2 = 29\\\\3x + 17 = 29\\\\Subtract \ 17 \ to \ both \ sides\\\\3x = 29-17\\\\3x = 12\\\\Divide \ 3 \ to \ both \ sides\\\\x = 12 / 3\\\\x = 4\\\\Take \ square \ on \ both \ sides\\\\x^2 = (4)^2\\\\x^2 = 16\\\\\rule[225]{225}{2}[/tex]
Hope this helped!
