Answer:
3^4 because when u divide exponents w same base just subtract the exponents
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
The LCM is 90 because once you fill out the pattern which would be 45x1 45x2 45x3 and so on and 2x1 2x2 2x3 and so on you will eventually meet at 90.
Check the picture below.
so hmmm let's find the distance AC, which is the only one missing for the perimeter.

Answer:
(m−5)(2m−2)
=(m+−5)(2m+−2)
=(m)(2m)+(m)(−2)+(−5)(2m)+(−5)(−2)
=2m2−2m−10m+10
=2m2−12m+10
Answer:
She rewrote the problem without parentheses: x3+ 2x2 - x + x3 – 2x2 +6
Step-by-step explanation:
It looks like she didn't fully distribute the -
(x3 + 2x2 - x)-(-x3 + 2x2 + 6) :Original
x3+ 2x2 - x + x3 – 2x2 +6 :Changed
~
(x3 + 2x2 - x)-(-x3 + 2x2 + 6)
x3 + 2x2 - x + x3 - 2x2 - 6
x3 + x3 + 2x2 - 2x2 -x - 6
2x3-x-6
I hope this helps ^-^
