Answer 1

Answer:

a = 360

and

b = 84/5.......

Answer 2

$\large{\underline{\underline{\mathfrak{\green{\bf{Solution:-}}}}}}$.

$\large{\underline{\underline{\mathfrak{\bf{Given\:here:-}}}}}$.

• $\:a\:=\frac{5x^2}{2}$

• $\:b\:=\frac{2x^2(x-5)}{10x}$

$\large{\underline{\underline{\mathfrak{\bf{Find\:here:-}}}}}$.

• Value of a and b , when x = 12.

Case 1.

$\large\boxed{\:a\:=\frac{5x^2}{2}}$

Keep value of x = 12 ,

$\implies\:a\:=\frac{5×(12^2)}{2}$

$\implies\:a\:=\frac{5×144}{2}$

$\boxed{\implies\:a\:=\:360}$

Now, again

$\large\boxed{\:b\:=\frac{2x^2(x-5)}{10x}}$

Keep Value of X = 12

$\implies\:b\:=\frac{2×(12^2)(12-5)}{10×12}$

$\implies\:b\:=\frac{2×144×7}{120}$

$\implies\:b\:=\frac{12×7}{5}$

$\implies\:b\:=\frac{84}{5}$

$\boxed{\implies\:b\:=\frac{84}{5}}$
