The answer is C. -4n⁴+3n.
Separate the expression by its like terms.
12n-2n⁴-10n-2n⁴+n
12n+(-10n)+n=3n
-2n⁴+-2n⁴=-4n⁴
The simplified expression comes out to -4n⁴+3n.
Answer:
C
Step-by-step explanation:
How many extra credit assignments does Blaire need to complete in order to pass?
A.
x > 236
B.
x > 59
C.
x > 472
D.
x > 8
Answer: D) x = 8
Step-by-step explanation: In order to get this answer, you need to keep the 236 and add 59 evry time until you get 708.
Another thing is to multiply 59 by 8, which will give you 472. Now we add 472 and 236 and we get 708.
59 x 8 = 472 + 236 = 708.
56 + 56 + 56 + 56 + 56 + 56 + 56 + 56 = 472 + 236 = 708.
Hope this helped!

Answer:
x>8
Step-by-step explanation:
I only answered so the other guy could get brainliest.
7 kilometers per 1 week equals 8.75 kilometers per x weeks.
7 / 1 = 8.75 / x
7 = 8.75 / x
7x = 8.75
x = 8.75 / 7
x = 1.25
It took 1.25 weeks to build 8.75 kilometers of road.
The construction crew would need approximately 1.25 weeks to build 8.75 kilometers of road. This is calculated by dividing the total distance by the rate of construction.
To find out how many weeks it took the construction crew to build 8.75 kilometers of road, we need to divide the total distance (8.75 km) by the rate at which they built the road (7 km per week). So, the calculation will be 8.75 km ÷ 7 km/week.
This is a simple division problem. Using a calculator, you will find that 8.75 ÷ 7 equals approximately 1.25.
Therefore, the construction crew would need about 1.25 weeks to build 8.75 kilometers of road. Please note, this is an approximation, and actual times may vary.
