Answer: 51
Step-by-step explanation: (sqrt(2))^2 + 7^2
The squareroot and square cancel, leaving 2. 7^2=7*7=49
49+2=51
The answer is 5a pretty sure
Answer:
Step-by-step explanation:
g(x) = (x+4)² - 5
a = interest rate of first CD
b = interest rate of second CD
and again, let's say the principal invested in each is $X.

To find the sum of the interior angles you use the formula (n-2)(180), where n is the number of sides. In this case, the number of sides is 12, so you get 1800 degrees. Then you divide by number of angles which is 12. So your answer is 150 degrees.
