Answer: 10.2
Step-by-step explanation:
b = 15² - 11²
= 225 - 121
= 104
= √104
= 10.2
To find the perfect square of an equation, you just take your "middle" term (in this case, 16), divide it by 2, then square it.
16/2 = 8
8^2 = 64
your perfect square is 64. you can check it really quick by trying to factor x^2 + 16x + 64 and seeing that it breaks down perfectly into (x + 8)(x + 8), which can be written as (x + 8)^2, showing that you have a binomial with a perfect square!!
