Answer:

35

Step-by-step explanation:

To find his total score in the quiz, we need to add all the scores he had in successive rounds.

This gives a value of; 25 + (-5) + (-10) + 15 + 10 = 25-5-10+15+10 = 25 + 10 = 35

Thus his total score at the end is 35

I<u>dentity</u>

(a - b)² = a² - 2ab + b²

Find the product

(x√7 - 3√8)² =  (x√7)² - 2*x√7*3√8 +(3√8)²

 = 7x² - 6x√56 + 72

 = 7x² - 6x*2√14 + 72

 = 7x² - 12x√14 + 72

Therefore the correct answer is option B).  7x² - 12x√14 + 72
