$(2+\sqrt{5})^{2}=?+4 \sqrt{5}$

One-fifth of a number is equal to $\frac{5}{8}$ of another number. If $35$ is added to the first number,it becomes four times the second number. The second number is

$(0.88 \times 880 \div 8) \times 6 = ?$

In a division sum,the divisor is $4$ times the quotient and twice the remainder. If $a$ and $b$ are respectively the divisor and the dividend,then

The product of two numbers is $45$ and the sum of their squares is $106$. The numbers are

$(13.99)^{2} - (15.02)^{2} + (18.07)^{2} - 36.64 = ?$
