X=58 the exterior angle is “D” 60degrees
Answer:
146%
Step-by-step explanation:

If the percent change is positive, it is a percent increase.
If the percent change is negative, it is a percent decrease.
Your numbers are
old price = $0.92
new price = $2.26
Plug in the numbers in the formula above and evaluate the expression.
percent change = ($2.26 - $0.92)/($0.92) * 100%
percent change = ($1.34)/($0.92) * 100%
percent change = 1.4565 * 100%
percent change = 146%
Since the percent change is a positive number, it is a percent increase.
Answer: The percent increase is 146%.
Answer:
D. The work shown above is correct, and
may not be simplified further.
Step-by-step explanation:
If you add all the exponents of y in first line then we get
4+4+4+4+4+3=23
Which is same as the exponent in original problem.
So first line is good.
Since it is 4th root so each
will turn into y when it moves out of the radical so final answer is correct.
Hence correct choice is "D. The work shown above is correct, and
may not be simplified further." is the correct answer.
12 x 24= 288 288 x 10 = 2,880 2,880 cubic centimeters
