Answer:
The answer is B. 105 miles
Step-by-step explanation:
I just used a calculator and put in 30 times a random number until I got 63. So, 30 times 2.1 is 63. Then, I multiplied 50 times 2.1 to get 105 as the answer.

To find that one, just look at the highest exponent. In the given equation that would be 4, so there can be at most 4 zeros in this function.
The largest number that 8c could be is -15
For Part A, you need to input x=6 into the equation 8x + 8 = 56 to see if 6 is a solution of that equation. It'll be 8(6) + 8 = 56 -> 48 + 8 = 56 -> 56 = 56. Does 56 equal 56? Then yes, x = 6 is a solution of the equation 8x + 8 = 56.
For Part B, it changed the value of x from 6 to 9. It also states that the left side of the equation (left side of the equal sign) stays the same so it'll still be 8x + 8. You do what you did in Part A, but instead of inputting 6, you do 9. It'll be like this: 8(9) + 8. It's asking how the right side would change, but that's basically asking what the answer is. If you do the math correctly, it'd be 72+8, which would be 80. The right side would need to be 80 if the solution is now x = 9.
486, (1/3) times 486 = 162, (1/3) times 162 = 54, (1/3) times 54 = 18
so answer is D
