1) the ones digit stays at 2 the tens increase by 1.
The area is 100 I think because the length and height is 10 right hope this helps
(-a^3b^2*-a^-2b^-3)^-2/2a^2b^-3
= a^4b^9/2a^8b^4
=b^5/2a^4
so your answer is b^5/2a^4
So what you do,is you add them together to get 13/10 but then you can also simplify it but you can keep the answer to 13/10
8hrs = 480mins
6hrs = 360 mins
472/480 = 0.983...
0.983... x 360 = 354
D) 354
