Knock knock....?
Anyone here..?✋✋
Sam's question.... X is defined as 30% of 30. If Y= x²+4x+7... Find Y???

Answer 1

x = 30% of 30
x = 30/100*30
x= 9

Y =x²+4x+7
using value of x we get
9²+4×9+7
=81+36+7
=124

Answer 2

Solution:-

$\bold{x = \frac{30}{100} \times 30}$

$\bold{ \implies \: x = \frac{900}{100} }$

$\boxed{ \red{ \bold{ \implies \: x = 9}}}$

$\textsf{Now, we need to find y}$

$\bold{y = x {}^{2} +4x+7}$

$\textsf{Now, by putting the value of x}$

$\bold{y = (9) {}^{2} + 4(9) + 7}$

$\bold{ \implies \: y = 81 + 36 + 7}$

$\boxed{ \bold \red{ \implies \: y = 124}}$

$\textsf{Therefore, x= 9 and y= 124}$
