D- 40d- 40 because a^2 + b^2 = c^2. 9^2 +b^2 = 41^2. 41^2 = 1681, 9^2 = 81. 1681-81= 1600. b^2 = 1600. Sqrt(1600)= 40. 40=b
Answer:
2 10 8
Step-by-step explanation:
The answer is 46.11, I hope, dunno what the 5.51 is but if you use the formula to find the pentagon area which is very complicated ( i suggest you google it) and plug 8 for a you get 46.11

Complete question is:
Nancy is checking to determine if the expressions x+4+x and 6+2x-2 are equivalent. When x=3 , she correctly finds that both expressions have a value of 10. When x = 5, she correctly evaluates the first expression to find that x + 4 + x = 14. What about the second expression?
Answer:
when x = 5; both expressions are equivalent and equal to 14
Step-by-step explanation:
We are told the expressions are:
(x + 4 + x) and (6 + 2x - 2).
We are also told that when x = 3,both expressions are equal and have a value of 10 each.
Now, when x = 5; we are told the expression (x + 4 + x) has a value of 14.
So when x = 5,let's find the value of the second expression by putting 5 for x in (6 + 2x - 2);
So, we have; 6 + 2(5) - 2 = 6 + 10 - 2 = 14
So when x = 5; both expressions are equivalent and equal to 14
