Answer: The answer should be 38.
I also saw that you placed a t after the -2 so I wasn't sure if it was a mistake or if it was on purpose or you left another t out of the problem on accident.
Step-by-step explanation:
2.3 (14+6) -2 to the power of three
2.3 (20) -2 to the power of three
2.3 (20) -8
46-8
38
I really hoped this helped and if I got it wrong with the t just reply to me c:

Just to be sure, substitute with x = 2 in the equation.
Answer: 29 feet.
Step-by-step explanation: The formula for the circumference of a circle is C = π d. In order to calculate the diameter of the tree we will use the same formula and solve for d.
91 = 3.14 x d
In order to solve for d you need to divide both sides for 3.14:
D = 28.98, rounded to the nearest foot is 29 feet.
