Hi again, could you check another one of my answers?

Your answer is correct! Total earnings would be 6t+2 + 9t-6 = 15t-4.

I have another answer for you to check!

144^14/144^2

A: 144^16 (my answer)
B: 144^12
C: 144^28
D: 144^14/2

I'm sorry but your answer is incorrect. When dividing exponents with the same base, we subtract the exponents. So, 144^14/144^2 = 144^(14-2) = 144^12. Therefore, the correct answer is B) 144^12.

Okay thanks for teaching me how to learn from my mistake.

You're welcome! It's important to learn from mistakes, and I'm glad to help you. Don't hesitate to ask if you have any more questions or need help with anything else!

x^16/x3

A: x^16/3
B: x^48
C: x^19
D: x^13 (my answer)

I'm sorry but your answer is incorrect. When dividing with exponents of the same base, you must subtract the exponent in the denominator from the exponent in the numerator. Therefore,

x^16/x^3 = x^(16-3) = x^13

So the correct answer is D) x^13.
