Question

If 3(x-5)+2=29, the value of x^2 is​

Answer 1

Explanation:

`\huge{\underline{\underbrace{\mathcal\color{gold}{Answer}}}}`

`\tt{3(x-5)+2=29 }` ⠀

`\tt{3x-15=29-2 }` ⠀

`\tt{ 3x=27-15 }` ⠀

`\tt{ 3x=12 }` ⠀

`\tt{ x=(12)/(3) }` ⠀

`\tt{x=4 }` ⠀

So,

According to the question,

`\tt{ x^2=x×x=4×4=16}` ⠀

Answer 2

`\huge\boxed{\sf x^2 = 16}`

Explanation:

`\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}`

Hope this helped!
