A; first equation is the red one and second is the blue one
I believe it’s 5,832,000
5^3 (5 times 5= 25 times 5= 125)^6(750 times 6= 4,500 etc)

Collecting like terms,

Since the signs change when its position changes.

Answer:
11.
Step-by-step explanation:
(2(n-3))-4=12
(2n-6)-4=12 <em>distribute</em>
2n-6-4=12
2n-10=12
2n=12+10 <em>isolate</em><em> </em><em>n</em><em> </em>
2n=22
2n÷2=22÷2
n=11
