If I turned 9 on November 9th, 2015, exactly how old am I now? (Oct 16th, 2021)
inysia [295]

The answer to this is quite simple my friend.

So if you were 9, purely turning on November 9th of 2015 at a undisclosed time, you would've been born in November of 2006. Currently, now of October 16, 2021, you would be:

Add:

4 + 10 + 1 = 15

So you would be 15 years old.

Hope this helps, currently it's 10/17/2021 for me and 1:56 am (EST).

Have a nice morning, night, dusk etc.

Simplify the expression. Rewrite using only positive exponents.
Afina-wow [57]

Answer:

The answer is D

Step-by-step explanation:

((c^6d^5e^4)*(c^-3de^-2))^2\\

Reorder the terms

= ((e^4c^6d^5)*(e^-2c^-3d))^2\\

Calculate

= (e^4c^6d^5e^-2c^-3d)^2

Use the properties of exponents

= (e^2c^3d^6)^2

Therefore, the answer is c^6 d^12 e^4 or D

frez [133]
Steps:
"Of" means "x" (times)
For 20% pretend there is an imaginary decimal at the end and move that decimal all the way to the front.

Now what is .20 of (times) $60 = 12

I think that's what you wanted. The discount price
