Answer:
n=-4
Step-by-step explanation:
-6n-(-2n)=16
-6n+2n=16
-4n=16
n=16/-4
n=-4
Take 15% of 400, or 0.15 x 400
0.15 x 400 = 60
However, $60 is only the 15%.
Now, take away 60 from 400.
400 - 60 = 340.
So $340 went towards the trip.
For number 3, it is reciprocal
and for number 4, it is whole number
It would be 443 bc you would subtract by 6 2x
Answer: 1,070 cm²
Step-by-step explanation:
25 multiplied by 15 is 375.
15 multiplied by 4 is 60.
25 multiplied by 4 is 100.
Now, we multiply these answers by 2.
375 multiplied by 2 is 750.
100 multiplied by 2 is 200.
60 multiplied by 2 is 120.
Add these all up, and you get your surface area, 1,070.
(Tldr; SA = 2lw + 2lh + 2hw)
