Question

If 3(x-5)+2=29, the value of x^2 is​

Answer 1

Answer:

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

Step-by-step explanation:

$\sf 3(x+5) +2 = 29\\\\Resolving \ Parenthesis\\\\ 3x + 15 + 2 = 29\\\\3x + 17 = 29\\\\Subtract \ 17 \ to \ both \ sides\\\\3x = 29-17\\\\3x = 12\\\\Divide \ 3 \ to \ both \ sides\\\\x = 12 / 3\\\\x = 4\\\\Take \ square \ on \ both \ sides\\\\x^2 = (4)^2\\\\x^2 = 16\\\\\rule[225]{225}{2}$

Answer 2

Step-by-step explanation:

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

$\tt{3(x-5)+2=29 }$ ⠀

$\tt{3x-15=29-2 }$ ⠀

$\tt{ 3x=27-15 }$ ⠀

$\tt{ 3x=12 }$ ⠀

$\tt{ x=\dfrac{12}{3} }$ ⠀

$\tt{x=4 }$ ⠀

So,

According to the question,

$\tt{ x^2=x×x=4×4=16}$ ⠀
