= 81+ 36 + 7.

= 124.

Thank you. Have a good day ahead.

Answer 2

Answer:

x = 9

and

y = 124

Step-by-step explanation:

x is defined as 30% of 30

$30\% \: of \: 30 = \frac{30}{100} \times 30 = 9$

Therefore ,

x = 9

Now ,

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

$y = {9}^{2} + 4 \times 9 + 7$

$y = 81 + 36 + 7$

$y = 124$

Therefore ,

y = 124
