The given expression is in the form (a+b)(a-b) where
a = 5
b = sqrt(3)
Recall that
(a+b)(a-b) = a^2-b^2
is the difference of squares formula
If a = 5, then a^2 = 25
If b = sqrt(3), then b^2 = (sqrt(3))^2 = 3
The squaring undoes the square root. The two opposites cancel out.
So using a^2 = 25 and b^2 = 3, we can say
(a+b)(a-b) = a^2-b^2 = 25-3 = 22
Therefore,
(5+sqrt(3))(5-sqrt(3)) = 22
Answer: B) 22

Answer:
60.2 miles.
Step-by-step explanation:
43 / 2.5 = 17.2 << unit rate
17.2 x 3.5 = 60.2
1-10=-9 You could look at a number line and find positive 1 and count downwards to negative 9 to get ten so the answer is
