Answer:

3

Step-by-step explanation:

$(\sqrt{5} - \sqrt{2})(\sqrt{2} + \sqrt{5})\\\sqrt{5} (\sqrt{2} + \sqrt{5}) - \sqrt{2} (\sqrt{2} + \sqrt{5})\\\sqrt{5} * \sqrt{2} + \sqrt{5} * \sqrt{5} - \sqrt{2} * \sqrt{2} +\sqrt{2} * \sqrt{5}\\ \sqrt{5*2} + \sqrt{5*5} - \sqrt{2*2} - \sqrt{2*5}\\\sqrt{10} + \sqrt{25} - \sqrt{4} - \sqrt{10}$

plus root 10 and minus root 10 gets cancel . So,

$\sqrt{25} - \sqrt{4} \\\sqrt{5^{2} } - \sqrt{2^{2} }$

square and root gets cancel

"five times the sum of a number and 6 is 48"

makvit [3.9K]

Answer:

Sum of the number is 8.4

Step-by-step explanation:

x = sum of a number

(5 × x) + 6 =48

5x + 6 = 48

5x + (6 - 6) = (48 - 6)

5x = 42

5x ÷ 5 = 42 ÷ 5

x = 8.4
